🔗 Problem

Problem: In their game, Kyle threw a ball for a distance of 18/4 yards, while Lisa threw the same ball for a distance of 19/9 yards. How many yards did the ball travel in total?

GPT-4o:

To find the total distance the ball traveled, we need to add the distances thrown by Kyle and Lisa.

First, let's convert the fractions to a common denominator. The denominators are 4 and 9. The least common multiple (LCM) of 4 and 9 is 36.

Convert \( \frac{18}{4} \) to a fraction with a denominator of 36:
\[ \frac{18}{4} = \frac{18 \times 9}{4 \times 9} = \frac{162}{36} \]

Convert \( \frac{19}{9} \) to a fraction with a denominator of 36:
\[ \frac{19}{9} = \frac{19 \times 4}{9 \times 4} = \frac{76}{36} \]

Now, add the two fractions:
\[ \frac{162}{36} + \frac{76}{36} = \frac{162 + 76}{36} = \frac{238}{36} \]

Simplify the fraction \( \frac{238}{36} \):
\[ \frac{238 \div 2}{36 \div 2} = \frac{119}{18} \]

Thus, the total distance the ball traveled is \( \frac{119}{18} \) yards.

### Answer: \( \frac{119}{18} \) yards

Expected answer: 119/18

Correct? Yes

Problem: After both Kyle and Lisa's throws, the ball bounced an additional 3/13 yards. Subtract this distance from the total distance the ball traveled when Kyle and Lisa threw it. What is the remaining distance?

GPT-4o:

To find the remaining distance after subtracting the additional bounce, we need to subtract \( \frac{3}{13} \) yards from the total distance \( \frac{119}{18} \) yards.

First, we need a common denominator for the fractions \( \frac{119}{18} \) and \( \frac{3}{13} \). The least common multiple (LCM) of 18 and 13 is 234.

Convert \( \frac{119}{18} \) to a fraction with a denominator of 234:
\[ \frac{119}{18} = \frac{119 \times 13}{18 \times 13} = \frac{1547}{234} \]

Convert \( \frac{3}{13} \) to a fraction with a denominator of 234:
\[ \frac{3}{13} = \frac{3 \times 18}{13 \times 18} = \frac{54}{234} \]

Now, subtract the two fractions:
\[ \frac{1547}{234} - \frac{54}{234} = \frac{1547 - 54}{234} = \frac{1493}{234} \]

Simplify the fraction \( \frac{1493}{234} \):
Since 1493 and 234 have no common factors other than 1, the fraction is already in its simplest form.

Thus, the remaining distance is \( \frac{1493}{234} \) yards.

### Answer: \( \frac{1493}{234} \) yards

Expected answer: 1493/234

Correct? Yes

Problem: In their game, suppose that Kyle actually threw the ball for a distance of 15/4 yards, while Lisa still threw the ball for 19/9 yards. How many yards did the ball travel in total now?

GPT-4o:

To find the total distance the ball traveled, we need to add the distances thrown by Kyle and Lisa.

First, let's convert the fractions to a common denominator. The denominators are 4 and 9. The least common multiple (LCM) of 4 and 9 is 36.

Convert \( \frac{15}{4} \) to a fraction with a denominator of 36:
\[ \frac{15}{4} = \frac{15 \times 9}{4 \times 9} = \frac{135}{36} \]

Convert \( \frac{19}{9} \) to a fraction with a denominator of 36:
\[ \frac{19}{9} = \frac{19 \times 4}{9 \times 4} = \frac{76}{36} \]

Now, add the two fractions:
\[ \frac{135}{36} + \frac{76}{36} = \frac{135 + 76}{36} = \frac{211}{36} \]

Thus, the total distance the ball traveled is \( \frac{211}{36} \) yards.

### Answer: \( \frac{211}{36} \) yards

Expected answer: 211/36

Correct? Yes

🔗 Problem

Problem: Johnnie the monkey was given 18/7 bananas by the zookeeper in the morning, and 12/14 bananas in the afternoon. In total, how many bananas were given to Johnnie the monkey?

GPT-4o:

First, we need to simplify the fractions given to Johnnie the monkey.

The fraction \( \frac{18}{7} \) is already in its simplest form.

Next, we simplify \( \frac{12}{14} \):
\[ \frac{12}{14} = \frac{12 \div 2}{14 \div 2} = \frac{6}{7} \]

Now, we add the two fractions:
\[ \frac{18}{7} + \frac{6}{7} \]

Since the denominators are the same, we can add the numerators directly:
\[ \frac{18 + 6}{7} = \frac{24}{7} \]

So, the total number of bananas given to Johnnie the monkey is \( \frac{24}{7} \).

### Answer: \(\frac{24}{7}\)

Expected answer: 24/7

Correct? Yes

🔗 Follow-up

Problem: In addition to the bananas given to Johnnie the monkey in the morning and afternoon, the zookeeper decides to give Johnnie the same total amount of bananas the next day. How many bananas in total did Johnnie the monkey receive over these two days?

GPT-4o:

We already determined that Johnnie the monkey received \( \frac{24}{7} \) bananas in one day.

Since the zookeeper decides to give Johnnie the same amount of bananas the next day, we need to calculate the total amount of bananas over two days.

We multiply the amount of bananas received in one day by 2:
\[ 2 \times \frac{24}{7} = \frac{2 \times 24}{7} = \frac{48}{7} \]

So, the total number of bananas Johnnie the monkey received over these two days is \( \frac{48}{7} \).

### Answer: \(\frac{48}{7}\)

Expected answer: 48/7

Correct? Yes

🔗 Problem

Problem: The bottom of a door measures 4/19 inches from the floor, and the top of the door measures 9/10 inches from the ceiling. What is the total distance of the bottom and top of the door from the floor and ceiling, respectively?

GPT-4o:

To find the total distance of the bottom and top of the door from the floor and ceiling, respectively, we need to add the two given measurements.

The bottom of the door is 4/19 inches from the floor.
The top of the door is 9/10 inches from the ceiling.

First, we need to find a common denominator to add these fractions. The least common multiple of 19 and 10 is 190.

Convert each fraction to have a denominator of 190:
\[ \frac{4}{19} = \frac{4 \times 10}{19 \times 10} = \frac{40}{190} \]
\[ \frac{9}{10} = \frac{9 \times 19}{10 \times 19} = \frac{171}{190} \]

Now, add the two fractions:
\[ \frac{40}{190} + \frac{171}{190} = \frac{40 + 171}{190} = \frac{211}{190} \]

Since \(\frac{211}{190}\) is an improper fraction, we can convert it to a mixed number:
\[ \frac{211}{190} = 1 \frac{21}{190} \]

Thus, the total distance of the bottom and top of the door from the floor and ceiling, respectively, is:
\[ 1 \frac{21}{190} \] inches.

### Answer: 1 \(\frac{21}{190}\) inches.

Expected answer: 211/190

Correct? Yes

🔗 Follow-up

Problem: If we consider the distance from the floor and ceiling for both the front and back doors, which have the same measurements as the original door, what is the total distance considering the bottoms and tops of both doors from the floor and ceiling respectively?

GPT-4o:

To find the total distance considering the bottoms and tops of both the front and back doors from the floor and ceiling, we need to double the distance we calculated for one door.

From the previous calculation, the total distance for one door is:
\[ 1 \frac{21}{190} \] inches.

To find the total distance for both doors, we multiply this distance by 2.

First, convert the mixed number to an improper fraction:
\[ 1 \frac{21}{190} = \frac{190}{190} + \frac{21}{190} = \frac{211}{190} \]

Now, multiply by 2:
\[ 2 \times \frac{211}{190} = \frac{2 \times 211}{190} = \frac{422}{190} \]

Convert the improper fraction back to a mixed number:
\[ \frac{422}{190} = 2 \frac{42}{190} \]

Simplify the fraction \(\frac{42}{190}\):
\[ \frac{42}{190} = \frac{21}{95} \]

Thus, the total distance considering the bottoms and tops of both doors from the floor and ceiling, respectively, is:
\[ 2 \frac{21}{95} \] inches.

### Answer: 2 \(\frac{21}{95}\) inches.

Expected answer: 211/95

Correct? Yes

🔗 Follow-up

Problem: If we reconsider the original scenario with the bottom of a door measuring 4/16 inches from the floor instead of 4/19 inches, and the top still measuring 9/10 inches from the ceiling, what is the new total distance of the bottom and top of the door from the floor and ceiling, respectively?

GPT-4o:

To find the new total distance of the bottom and top of the door from the floor and ceiling, respectively, we need to add the two given measurements.

The bottom of the door is now \( \frac{4}{16} \) inches from the floor.
The top of the door is \( \frac{9}{10} \) inches from the ceiling.

First, simplify \( \frac{4}{16} \):
\[ \frac{4}{16} = \frac{1}{4} \]

Next, we need to find a common denominator to add \( \frac{1}{4} \) and \( \frac{9}{10} \). The least common multiple of 4 and 10 is 20.

Convert each fraction to have a denominator of 20:
\[ \frac{1}{4} = \frac{1 \times 5}{4 \times 5} = \frac{5}{20} \]
\[ \frac{9}{10} = \frac{9 \times 2}{10 \times 2} = \frac{18}{20} \]

Now, add the two fractions:
\[ \frac{5}{20} + \frac{18}{20} = \frac{5 + 18}{20} = \frac{23}{20} \]

Since \( \frac{23}{20} \) is an improper fraction, we can convert it to a mixed number:
\[ \frac{23}{20} = 1 \frac{3}{20} \]

Thus, the new total distance of the bottom and top of the door from the floor and ceiling, respectively, is:
\[ 1 \frac{3}{20} \] inches.

### Answer: 1 \(\frac{3}{20}\) inches.

Expected answer: 23/20

Correct? Yes

🔗 Problem

Problem: Ralph's juice recipe requires 17/3 liters of apple juice. However, he only uses 15/11 liters of it. How many liters of apple juice are left unused?

GPT-4o:

To determine how many liters of apple juice are left unused, we need to subtract the amount Ralph used from the amount required by the recipe.

First, let's convert the fractions to a common denominator to make the subtraction easier. The denominators are 3 and 11. The least common multiple (LCM) of 3 and 11 is 33.

Convert \( \frac{17}{3} \) to a fraction with a denominator of 33:
\[ \frac{17}{3} = \frac{17 \times 11}{3 \times 11} = \frac{187}{33} \]

Convert \( \frac{15}{11} \) to a fraction with a denominator of 33:
\[ \frac{15}{11} = \frac{15 \times 3}{11 \times 3} = \frac{45}{33} \]

Now, subtract the two fractions:
\[ \frac{187}{33} - \frac{45}{33} = \frac{187 - 45}{33} = \frac{142}{33} \]

Thus, the amount of apple juice left unused is \( \frac{142}{33} \) liters.

### Answer: \( \frac{142}{33} \) liters

Expected answer: 142/33

Correct? Yes

🔗 Follow-up

Problem: After finishing his juice recipe, Ralph decides to add an additional 3/18 liters of apple juice to the mix. How many liters of unused apple juice are left now?

GPT-4o:

To determine how many liters of unused apple juice are left after Ralph adds an additional \( \frac{3}{18} \) liters to the mix, we need to subtract this additional amount from the previously calculated unused amount.

First, simplify \( \frac{3}{18} \):
\[ \frac{3}{18} = \frac{1}{6} \]

Next, we need to subtract \( \frac{1}{6} \) from \( \frac{142}{33} \). To do this, we need a common denominator. The least common multiple (LCM) of 33 and 6 is 198.

Convert \( \frac{142}{33} \) to a fraction with a denominator of 198:
\[ \frac{142}{33} = \frac{142 \times 6}{33 \times 6} = \frac{852}{198} \]

Convert \( \frac{1}{6} \) to a fraction with a denominator of 198:
\[ \frac{1}{6} = \frac{1 \times 33}{6 \times 33} = \frac{33}{198} \]

Now, subtract the two fractions:
\[ \frac{852}{198} - \frac{33}{198} = \frac{852 - 33}{198} = \frac{819}{198} \]

Simplify \( \frac{819}{198} \) by finding the greatest common divisor (GCD) of 819 and 198, which is 9:
\[ \frac{819 \div 9}{198 \div 9} = \frac{91}{22} \]

Thus, the amount of apple juice left unused after adding the additional \( \frac{1}{6} \) liters is \( \frac{91}{22} \) liters.

### Answer: \( \frac{91}{22} \) liters

Expected answer: 91/22

Correct? Yes

GPT-4o:

To determine how many liters of apple juice are left unused, we need to subtract the amount Ralph used from the amount he initially had.

First, let's convert the fractions to a common denominator to make the subtraction easier. The denominators are 3 and 11. The least common multiple (LCM) of 3 and 11 is 33.

Convert \( \frac{17}{3} \) to a fraction with a denominator of 33:
\[ \frac{17}{3} = \frac{17 \times 11}{3 \times 11} = \frac{187}{33} \]

Convert \( \frac{14}{11} \) to a fraction with a denominator of 33:
\[ \frac{14}{11} = \frac{14 \times 3}{11 \times 3} = \frac{42}{33} \]

Now, subtract the two fractions:
\[ \frac{187}{33} - \frac{42}{33} = \frac{187 - 42}{33} = \frac{145}{33} \]

Thus, the amount of apple juice left unused is \( \frac{145}{33} \) liters.

### Answer: \( \frac{145}{33} \) liters

🔗 Problem

Problem: Billy is trying to roller skate in an empty parking lot. He initially travels 4 miles, but rolls back for 17/20 of a mile after spotting a pothole. How many miles did he ultimately travel forward?

GPT-4o:

To determine how many miles Billy ultimately traveled forward, we need to subtract the distance he rolled back from the initial distance he traveled.

1. Billy initially travels 4 miles.
2. He rolls back 17/20 of a mile.

First, convert the fraction to a decimal to make the subtraction easier:
\[ \frac{17}{20} = 0.85 \]

Now, subtract the distance rolled back from the initial distance:
\[ 4 - 0.85 = 3.15 \]

Thus, Billy ultimately traveled forward 3.15 miles.

### Answer: 3.15 miles

Expected answer: 63/20

🔗 Problem

Problem: A rocket was launched into orbit. On the first day, it traveled 15/3 light years. On the second day, it traveled an additional 2/7 light years. How far has the rocket traveled in total?

GPT-4o:

First, we need to calculate the distance the rocket traveled on the first day. The distance is given as \( \frac{15}{3} \) light years.

\[
\frac{15}{3} = 5 \text{ light years}
\]

Next, we know the rocket traveled an additional \( \frac{2}{7} \) light years on the second day.

To find the total distance traveled, we add the distances from both days:

\[
5 + \frac{2}{7}
\]

To add these, we convert 5 into a fraction with a common denominator of 7:

\[
5 = \frac{35}{7}
\]

Now, we add the fractions:

\[
\frac{35}{7} + \frac{2}{7} = \frac{37}{7}
\]

Thus, the total distance traveled by the rocket is \( \frac{37}{7} \) light years.

### Answer: \(\frac{37}{7}\) light years

Expected answer: 37/7

Correct? Yes

🔗 Follow-up

Problem: In a change of earlier data, it was discovered that the rocket only traveled 15/3 light years on the first day. However, on the second day, it actually covered 18/7 light years instead of 2/7 light years. With this new information, how far has the rocket traveled in total?

GPT-4o:

First, we calculate the distance the rocket traveled on the first day, which remains \( \frac{15}{3} \) light years.

\[
\frac{15}{3} = 5 \text{ light years}
\]

Next, we calculate the distance the rocket traveled on the second day, which is now \( \frac{18}{7} \) light years.

To find the total distance traveled, we add the distances from both days:

\[
5 + \frac{18}{7}
\]

To add these, we convert 5 into a fraction with a common denominator of 7:

\[
5 = \frac{35}{7}
\]

Now, we add the fractions:

\[
\frac{35}{7} + \frac{18}{7} = \frac{53}{7}
\]

Thus, the total distance traveled by the rocket is \( \frac{53}{7} \) light years.

### Answer: \(\frac{53}{7}\) light years

🔗 Problem

Problem: Captain Silverbeard found 10/13 of a treasure map at one shipwreck site and 16/19 of the same treasure map at another site. What is the total portion of the treasure map that he found?

GPT-4o:

To find the total portion of the treasure map that Captain Silverbeard found, we need to add the two fractions: \( \frac{10}{13} \) and \( \frac{16}{19} \).

First, we need to find a common denominator for the fractions. The least common multiple (LCM) of 13 and 19 is 247, since both are prime numbers.

Next, we convert each fraction to have the common denominator of 247:

\[
\frac{10}{13} = \frac{10 \times 19}{13 \times 19} = \frac{190}{247}
\]

\[
\frac{16}{19} = \frac{16 \times 13}{19 \times 13} = \frac{208}{247}
\]

Now, we add the two fractions:

\[
\frac{190}{247} + \frac{208}{247} = \frac{190 + 208}{247} = \frac{398}{247}
\]

Since \( \frac{398}{247} \) is an improper fraction, we can simplify it:

\[
\frac{398}{247} = 1 + \frac{151}{247}
\]

Thus, Captain Silverbeard found \( 1 + \frac{151}{247} \) of the treasure map, which is more than the whole map.

### Answer: \( 1 + \frac{151}{247} \)

Expected answer: 398/247

Correct? Yes

🔗 Follow-up

Problem: After Captain Silverbeard finds the portions of the treasure map, he discovers another piece on a third site which is 15/17 of the total map. What is the total portion of the treasure map that Captain Silverbeard has now?

GPT-4o:

To find the total portion of the treasure map that Captain Silverbeard has now, we need to add the previously found portion \( 1 + \frac{151}{247} \) to the new portion \( \frac{15}{17} \).

First, we convert \( 1 + \frac{151}{247} \) to a single fraction:
\[
1 + \frac{151}{247} = \frac{247}{247} + \frac{151}{247} = \frac{398}{247}
\]

Next, we need to add \( \frac{398}{247} \) and \( \frac{15}{17} \). To do this, we need a common denominator. The least common multiple (LCM) of 247 and 17 is 4199 (since 247 = 13 * 19 and 17 is prime).

We convert each fraction to have the common denominator of 4199:

\[
\frac{398}{247} = \frac{398 \times 17}{247 \times 17} = \frac{6766}{4199}
\]

\[
\frac{15}{17} = \frac{15 \times 247}{17 \times 247} = \frac{3705}{4199}
\]

Now, we add the two fractions:

\[
\frac{6766}{4199} + \frac{3705}{4199} = \frac{6766 + 3705}{4199} = \frac{10471}{4199}
\]

Since \( \frac{10471}{4199} \) is an improper fraction, we can simplify it:

\[
\frac{10471}{4199} = 2 + \frac{2073}{4199}
\]

Thus, Captain Silverbeard has \( 2 + \frac{2073}{4199} \) of the treasure map.

### Answer: \( 2 + \frac{2073}{4199} \)

Expected answer: 10471/4199

Problem: Suppose instead of finding 10/13 of the treasure map at the first shipwreck site, Captain Silverbeard found a larger piece which was 10/9 of the total map. Keeping the second portion from the other shipwreck site the same at 16/19, what is the total portion of the treasure map that he found now?

GPT-4o:

To find the total portion of the treasure map that Captain Silverbeard found, we need to add the two fractions: \( \frac{10}{9} \) and \( \frac{16}{19} \).

First, we need to find a common denominator for the fractions. The least common multiple (LCM) of 9 and 19 is 171, since 19 is a prime number and 9 is \(3^2\).

Next, we convert each fraction to have the common denominator of 171:

\[
\frac{10}{9} = \frac{10 \times 19}{9 \times 19} = \frac{190}{171}
\]

\[
\frac{16}{19} = \frac{16 \times 9}{19 \times 9} = \frac{144}{171}
\]

Now, we add the two fractions:

\[
\frac{190}{171} + \frac{144}{171} = \frac{190 + 144}{171} = \frac{334}{171}
\]

Since \( \frac{334}{171} \) is an improper fraction, we can simplify it:

\[
\frac{334}{171} = 1 + \frac{163}{171}
\]

Thus, Captain Silverbeard found \( 1 + \frac{163}{171} \) of the treasure map, which is more than the whole map.

### Answer: \( 1 + \frac{163}{171} \)

🔗 Problem

Problem: A hiker decides to walk 9/6 miles North before walking 2/16 miles East. How many miles has the hiker traveled in total?

GPT-4o:

First, we need to simplify the fractions to make the calculations easier.

For the distance walked North:
\[ \frac{9}{6} = \frac{3 \times 3}{3 \times 2} = \frac{3}{2} = 1.5 \text{ miles} \]

For the distance walked East:
\[ \frac{2}{16} = \frac{1 \times 2}{8 \times 2} = \frac{1}{8} \text{ miles} \]

Now, we add the two distances together:
\[ 1.5 \text{ miles} + \frac{1}{8} \text{ miles} \]

To add these, we need a common denominator. The least common multiple of 2 and 8 is 8.

Convert \(1.5\) to a fraction with a denominator of 8:
\[ 1.5 = \frac{3}{2} = \frac{3 \times 4}{2 \times 4} = \frac{12}{8} \]

Now add the fractions:
\[ \frac{12}{8} + \frac{1}{8} = \frac{12 + 1}{8} = \frac{13}{8} \]

Convert \(\frac{13}{8}\) back to a decimal:
\[ \frac{13}{8} = 1.625 \]

### Answer: 1.625 miles

Problem: In Jessica's sandbox, she has a pile of sand that is 16/9 cubic feet. She then removes 4/13 cubic feet of sand from the sandbox. How much sand does she have left in her sandbox?

GPT-4o:

To determine how much sand Jessica has left in her sandbox, we need to subtract the amount of sand she removed from the total amount of sand she initially had.

Jessica initially has \( \frac{16}{9} \) cubic feet of sand.
She removes \( \frac{4}{13} \) cubic feet of sand.

First, we need to find a common denominator to subtract these fractions. The least common multiple (LCM) of 9 and 13 is 117.

Convert \( \frac{16}{9} \) to a fraction with a denominator of 117:
\[ \frac{16}{9} = \frac{16 \times 13}{9 \times 13} = \frac{208}{117} \]

Convert \( \frac{4}{13} \) to a fraction with a denominator of 117:
\[ \frac{4}{13} = \frac{4 \times 9}{13 \times 9} = \frac{36}{117} \]

Now, subtract the two fractions:
\[ \frac{208}{117} - \frac{36}{117} = \frac{208 - 36}{117} = \frac{172}{117} \]

Simplify the fraction \( \frac{172}{117} \):
The greatest common divisor (GCD) of 172 and 117 is 1, so the fraction is already in its simplest form.

Thus, the amount of sand left in the sandbox is \( \frac{172}{117} \) cubic feet.

Problem: Jessica decided to add more sand to her sandbox. She adds an extra 19/15 cubic feet of sand to it. After this, how much sand does she now have in her sandbox?

GPT-4o:

To determine how much sand Jessica has in her sandbox after adding \( \frac{19}{15} \) cubic feet of sand, we need to add this amount to the sand she had left, which was \( \frac{172}{117} \) cubic feet.

First, we need to find a common denominator for the fractions \( \frac{172}{117} \) and \( \frac{19}{15} \). The least common multiple (LCM) of 117 and 15 is 1755.

Convert \( \frac{172}{117} \) to a fraction with a denominator of 1755:
\[ \frac{172}{117} = \frac{172 \times 15}{117 \times 15} = \frac{2580}{1755} \]

Convert \( \frac{19}{15} \) to a fraction with a denominator of 1755:
\[ \frac{19}{15} = \frac{19 \times 117}{15 \times 117} = \frac{2223}{1755} \]

Now, add the two fractions:
\[ \frac{2580}{1755} + \frac{2223}{1755} = \frac{2580 + 2223}{1755} = \frac{4803}{1755} \]

Simplify the fraction \( \frac{4803}{1755} \):
The greatest common divisor (GCD) of 4803 and 1755 is 3, so we divide both the numerator and the denominator by 3:
\[ \frac{4803 \div 3}{1755 \div 3} = \frac{1601}{585} \]

Thus, the amount of sand Jessica now has in her sandbox is \( \frac{1601}{585} \) cubic feet.

### Answer: \(\frac{1601}{585}\) cubic feet

Expected answer: 1601/585

Problem: In our previous scenario, let's say that Jessica initially had a smaller pile of sand that was 16/9 cubic feet. If she still removed 4/8 cubic feet of sand as before, how much sand does she now have left in her sandbox?

GPT-4o:

To determine how much sand Jessica has left in her sandbox, we need to subtract the amount of sand she removed from the total amount of sand she initially had.

Jessica initially has \( \frac{16}{9} \) cubic feet of sand.
She removes \( \frac{4}{8} \) cubic feet of sand.

First, simplify \( \frac{4}{8} \):
\[ \frac{4}{8} = \frac{1}{2} \]

Next, we need to convert both fractions to have a common denominator to perform the subtraction. The least common multiple (LCM) of 9 and 2 is 18.

Convert \( \frac{16}{9} \) to a fraction with a denominator of 18:
\[ \frac{16}{9} = \frac{16 \times 2}{9 \times 2} = \frac{32}{18} \]

Convert \( \frac{1}{2} \) to a fraction with a denominator of 18:
\[ \frac{1}{2} = \frac{1 \times 9}{2 \times 9} = \frac{9}{18} \]

Now, subtract the two fractions:
\[ \frac{32}{18} - \frac{9}{18} = \frac{32 - 9}{18} = \frac{23}{18} \]

Thus, the amount of sand left in the sandbox is \( \frac{23}{18} \) cubic feet.

### Answer: \(\frac{23}{18}\) cubic feet

Expected answer: 23/18

Problem: Jacob has a piece of rope that is 15/12 meters long and he adds a piece that is 17/17 meters long to it. What is the total length of the rope now?

GPT-4o:

First, let's simplify the fractions if possible.

The first piece of rope is \( \frac{15}{12} \) meters long. We can simplify this fraction by finding the greatest common divisor (GCD) of 15 and 12, which is 3:
\[ \frac{15 \div 3}{12 \div 3} = \frac{5}{4} \]

The second piece of rope is \( \frac{17}{17} \) meters long. Since the numerator and the denominator are the same, this fraction simplifies to 1:
\[ \frac{17}{17} = 1 \]

Now, we add the simplified lengths together:
\[ \frac{5}{4} + 1 \]

To add these fractions, we need a common denominator. The common denominator for 4 and 1 is 4:
\[ 1 = \frac{4}{4} \]

So, we rewrite the addition as:
\[ \frac{5}{4} + \frac{4}{4} = \frac{5 + 4}{4} = \frac{9}{4} \]

Thus, the total length of the rope is \( \frac{9}{4} \) meters.

### Answer: \(\frac{9}{4}\) meters

Problem: Jacob now wants to double the total length of the rope he has. If Jacob starts with the rope that is ((15 / 12) + (17 / 17)) meters long, and then adds another piece of the same length to it, what will be the total length of the combined ropes?

GPT-4o:

We already determined that the total length of the rope Jacob initially has is \( \frac{9}{4} \) meters.

To double this length, Jacob will add another piece of rope that is also \( \frac{9}{4} \) meters long.

We need to add these two lengths together:
\[ \frac{9}{4} + \frac{9}{4} \]

Since the denominators are the same, we can add the numerators directly:
\[ \frac{9 + 9}{4} = \frac{18}{4} \]

We can simplify \( \frac{18}{4} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
\[ \frac{18 \div 2}{4 \div 2} = \frac{9}{2} \]

Thus, the total length of the combined ropes is \( \frac{9}{2} \) meters.

Problem: Now, suppose Jacob starts with a piece of rope that is 7/12 meters long instead of 15/12 meters. If he still adds the rope piece that is 17/17 meters long to it, what is the total length of the rope now?

GPT-4o:

First, let's simplify the fractions if possible.

The first piece of rope is \( \frac{7}{12} \) meters long. This fraction is already in its simplest form.

The second piece of rope is \( \frac{17}{17} \) meters long. Since the numerator and the denominator are the same, this fraction simplifies to 1:
\[ \frac{17}{17} = 1 \]

Now, we add the lengths together:
\[ \frac{7}{12} + 1 \]

To add these fractions, we need a common denominator. The common denominator for 12 and 1 is 12:
\[ 1 = \frac{12}{12} \]

So, we rewrite the addition as:
\[ \frac{7}{12} + \frac{12}{12} = \frac{7 + 12}{12} = \frac{19}{12} \]

Thus, the total length of the rope is \( \frac{19}{12} \) meters.

Problem: Mark has 1 full pair of pants and another 13/4 pairs from various incomplete sets. How many pairs of pants does he have in total?

GPT-4o:

To determine the total number of pairs of pants Mark has, we need to add the full pair to the fractional pairs.

First, let's convert the mixed number \( \frac{13}{4} \) into an improper fraction:
\[ \frac{13}{4} = 3 \frac{1}{4} \]

Now, we add the full pair (which is 1) to the mixed number:
\[ 1 + 3 \frac{1}{4} = 1 + 3 + \frac{1}{4} = 4 + \frac{1}{4} = 4 \frac{1}{4} \]

So, Mark has \( 4 \frac{1}{4} \) pairs of pants in total.

Problem: Mark already had 1 full pair of pants and another 13/4 pairs from various incomplete sets. If he goes shopping and buys an additional 13/3 pairs of pants, how many pairs of pants does he have in total now?

GPT-4o:

To determine the total number of pairs of pants Mark has after his shopping trip, we need to add the pairs he already had to the pairs he bought.

First, let's convert the mixed number \( \frac{13}{4} \) into an improper fraction:
\[ \frac{13}{4} = 3 \frac{1}{4} \]

Next, let's convert the mixed number \( \frac{13}{3} \) into an improper fraction:
\[ \frac{13}{3} = 4 \frac{1}{3} \]

Now, we add the full pair (which is 1) to the mixed number \( 3 \frac{1}{4} \):
\[ 1 + 3 \frac{1}{4} = 1 + 3 + \frac{1}{4} = 4 + \frac{1}{4} = 4 \frac{1}{4} \]

Next, we add the pairs he bought \( 4 \frac{1}{3} \):
\[ 4 \frac{1}{4} + 4 \frac{1}{3} \]

To add these, we need a common denominator. The least common multiple of 4 and 3 is 12.

Convert \( 4 \frac{1}{4} \) to a fraction with a denominator of 12:
\[ 4 \frac{1}{4} = 4 + \frac{1}{4} = 4 + \frac{3}{12} = 4 \frac{3}{12} \]

Convert \( 4 \frac{1}{3} \) to a fraction with a denominator of 12:
\[ 4 \frac{1}{3} = 4 + \frac{1}{3} = 4 + \frac{4}{12} = 4 \frac{4}{12} \]

Now, add the two fractions:
\[ 4 \frac{3}{12} + 4 \frac{4}{12} = 4 + \frac{3}{12} + 4 + \frac{4}{12} = 8 + \frac{3}{12} + \frac{4}{12} = 8 + \frac{7}{12} = 8 \frac{7}{12} \]

So, Mark has \( 8 \frac{7}{12} \) pairs of pants in total.

To determine the total number of pairs of pants Mark has, we need to add the full pair to the fractional pairs.

First, let's convert the improper fraction \( \frac{9}{4} \) into a mixed number:
\[ \frac{9}{4} = 2 \frac{1}{4} \]

Now, we add the full pair (which is 1) to the mixed number:
\[ 1 + 2 \frac{1}{4} = 1 + 2 + \frac{1}{4} = 3 + \frac{1}{4} = 3 \frac{1}{4} \]

Problem: Miss Jenny stayed after school to grade papers. She spent 8/8 hours on one subject and an additional 20/19 hours on another subject. How long did she spend grading papers in total?

GPT-4o:

To find the total time Miss Jenny spent grading papers, we need to add the time she spent on each subject.

First, we note that 8/8 hours is equivalent to 1 hour.

Next, we add this to the time spent on the other subject, which is 20/19 hours.

To add these fractions, we need a common denominator. However, since 1 hour can be written as 19/19 hours, we can directly add the fractions:

\[ 1 \text{ hour} = \frac{19}{19} \text{ hours} \]

Now, add the two fractions:

\[ \frac{19}{19} + \frac{20}{19} = \frac{19 + 20}{19} = \frac{39}{19} \]

Simplify the fraction:

\[ \frac{39}{19} = 2 \frac{1}{19} \]

So, Miss Jenny spent a total of \( 2 \frac{1}{19} \) hours grading papers.

### Answer: 2 \(\frac{1}{19}\) hours

Problem: After grading papers, Miss Jenny spends an additional 1/12 hours organizing her lesson plans. How long did she spend in total between grading papers and organizing her lesson plans?

GPT-4o:

To find the total time Miss Jenny spent between grading papers and organizing her lesson plans, we need to add the time she spent on each activity.

From the previous calculation, we know she spent \( 2 \frac{1}{19} \) hours grading papers. This can be written as an improper fraction:

\[ 2 \frac{1}{19} = \frac{39}{19} \]

She also spent \( \frac{1}{12} \) hours organizing her lesson plans.

To add these fractions, we need a common denominator. The least common multiple of 19 and 12 is 228.

Convert each fraction to have the common denominator of 228:

\[ \frac{39}{19} = \frac{39 \times 12}{19 \times 12} = \frac{468}{228} \]

\[ \frac{1}{12} = \frac{1 \times 19}{12 \times 19} = \frac{19}{228} \]

Now, add the fractions:

\[ \frac{468}{228} + \frac{19}{228} = \frac{468 + 19}{228} = \frac{487}{228} \]

Simplify the fraction if possible. In this case, 487 and 228 have no common factors other than 1, so the fraction is already in its simplest form.

Thus, Miss Jenny spent a total of \( \frac{487}{228} \) hours on both activities.

To find the total time Miss Jenny spent grading papers with the new time for the second subject, we need to add the time she spent on each subject.

First, we note that 8/8 hours is equivalent to 1 hour.

Next, we add this to the time spent on the other subject, which is 20/13 hours.

To add these, we need a common denominator. The least common multiple of 1 and 13 is 13. So, we convert 1 hour to a fraction with a denominator of 13:

\[ 1 \text{ hour} = \frac{13}{13} \text{ hours} \]

Now, add the two fractions:

\[ \frac{13}{13} + \frac{20}{13} = \frac{13 + 20}{13} = \frac{33}{13} \]

Simplify the fraction:

\[ \frac{33}{13} = 2 \frac{7}{13} \]

Problem: A cloud was observed at a height of 12/3 kms, it later ascended by 15/12 kms. What was the resultant height of the cloud from the ground?

GPT-4o:

First, we need to simplify the given fractions to make the calculations easier.

The initial height of the cloud is given as \( \frac{12}{3} \) kilometers. Simplifying this fraction:
\[ \frac{12}{3} = 4 \text{ kilometers} \]

Next, the cloud ascended by \( \frac{15}{12} \) kilometers. Simplifying this fraction:
\[ \frac{15}{12} = \frac{5 \times 3}{4 \times 3} = \frac{5}{4} \text{ kilometers} \]

Now, we need to add the initial height and the ascended height to find the resultant height:
\[ 4 + \frac{5}{4} \]

To add these, we convert 4 into a fraction with the same denominator as \( \frac{5}{4} \):
\[ 4 = \frac{16}{4} \]

Now, we can add the two fractions:
\[ \frac{16}{4} + \frac{5}{4} = \frac{16 + 5}{4} = \frac{21}{4} \]

Converting \( \frac{21}{4} \) back to a mixed number:

To find the total distance Jack rides his scooter, we need to add the two distances together. 

First, let's simplify the fractions if possible:

1. The distance to the library is \( \frac{3}{9} \) of a mile. Simplifying \( \frac{3}{9} \):
   \[
   \frac{3}{9} = \frac{1}{3}

GPT-4o:

First, let's determine the total burn time for the logs. Each log burns for \( \frac{1}{16} \) of an hour, and there are 4 logs. Therefore, the total burn time for the logs is:
\[
4 \times \frac{1}{16} = \frac{4}{16} = \frac{1}{4} \text{ hour}
\]

Next, let's determine the total burn time for the twigs. Each twig burns for \( \frac{1}{12} \) of an hour, and there are 16 twigs. Therefore, the total burn time for the twigs is:
\[
16 \times \frac{1}{12} = \frac{16}{12} = \frac{4}{3} \text{ hours}
\]

Now, we add the total burn time for the logs and the twigs:
\[
\frac{1}{4} + \frac{4}{3}
\]

To add these fractions, we need a common denominator. The least common multiple of 4 and 3 is 12. Converting each fraction to have a denominator of 12, we get:
\[
\frac{1}{4} = \frac{3}{12} \quad \text{and} \quad \frac{4}{3} = \frac{16}{12}

First, let's determine the total burn time for the charcoal. Each piece of charcoal burns for \( \frac{1}{5} \) of an hour, and there are 8 pieces. Therefore, the total burn time for the charcoal is:
\[
8 \times \frac{1}{5} = \frac{8}{5} \text{ hours}
\]

Previously, we calculated the total burn time for the logs and twigs as \( \frac{19}{12} \) hours. Now, we need to add the burn time for the charcoal to this total.

To add \( \frac{19}{12} \) and \( \frac{8}{5} \), we need a common denominator. The least common multiple of 12 and 5 is 60. Converting each fraction to have a denominator of 60, we get:
\[

GPT-4o:

First, let's determine the total burn time for the logs. Each log burns for \( \frac{1}{16} \) of an hour, and there are 4 logs. Therefore, the total burn time for the logs is:
\[
4 \times \frac{1}{16} = \frac{4}{16} = \frac{1}{4} \text{ hour}
\]

Next, let's determine the total burn time for the twigs. Each twig burns for \( \frac{1}{12} \) of an hour, and there are 15 twigs. Therefore, the total burn time for the twigs is:
\[
15 \times \frac{1}{12} = \frac{15}{12} = \frac{5}{4} \text{ hours}
\]

Now, we add the total burn time for the logs and the twigs:
\[

Since the denominators are already the same, we can simply add the numerators:
\[

Problem: If a ring maker uses 12/16 ounces of a silver for the base of the ring and 16/2 ounces to make the rest of the ring, how many ounces of silver did the ring maker use in total?

GPT-4o:

First, let's simplify the fractions and perform the necessary calculations.

1. The amount of silver used for the base of the ring is given as \( \frac{12}{16} \) ounces. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
   \[
   \frac{12}{16} = \frac{12 \div 4}{16 \div 4} = \frac{3}{4} \text{ ounces}
   \]

2. The amount of silver used for the rest of the ring is given as \( \frac{16}{2} \) ounces. We can simplify this fraction by performing the division:
   \[
   \frac{16}{2} = 8 \text{ ounces}
   \]

3. To find the total amount of silver used, we add the two amounts together:
   \[
   \frac{3}{4} \text{ ounces} + 8 \text{ ounces}
   \]

4. To add these, we can convert \( 8 \) ounces to a fraction with a common denominator of 4:
   \[
   8 = \frac{8 \times 4}{1 \times 4} = \frac{32}{4}
   \]

5. Now, we add the fractions:
   \[
   \frac{3}{4} + \frac{32}{4} = \frac{3 + 32}{4} = \frac{35}{4} \text{ ounces}
   \]

6. Converting \( \frac{35}{4} \) to a mixed number:
   \[
   \frac{35}{4} = 8 \frac{3}{4} \text{ ounces}
   \]

### Answer: 8 \(\frac{3}{4}\) ounces

Problem: The ring maker decides to add an ornamental filigree to the ring, which requires an additional 18/20 ounces of silver. How many total ounces of silver did the ring maker use including the filigree?

GPT-4o:

To determine the total amount of silver used, including the ornamental filigree, we need to add the amount of silver used for the filigree to the amount already calculated.

1. We previously calculated that the ring maker used \( \frac{35}{4} \) ounces of silver for the base and the rest of the ring.

2. The additional silver required for the ornamental filigree is \( \frac{18}{20} \) ounces. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
   \[
   \frac{18}{20} = \frac{18 \div 2}{20 \div 2} = \frac{9}{10} \text{ ounces}
   \]

3. To add \( \frac{35}{4} \) ounces and \( \frac{9}{10} \) ounces, we need a common denominator. The least common multiple of 4 and 10 is 20.

4. Convert both fractions to have a denominator of 20:
   \[
   \frac{35}{4} = \frac{35 \times 5}{4 \times 5} = \frac{175}{20}
   \]
   \[
   \frac{9}{10} = \frac{9 \times 2}{10 \times 2} = \frac{18}{20}
   \]

5. Now, add the fractions:
   \[
   \frac{175}{20} + \frac{18}{20} = \frac{175 + 18}{20} = \frac{193}{20}
   \]

6. Converting \( \frac{193}{20} \) to a mixed number:
   \[
   \frac{193}{20} = 9 \frac{13}{20} \text{ ounces}
   \]

### Answer: 9 \(\frac{13}{20}\) ounces

Expected answer: 193/20

Problem: If initially, the ring maker used 10/16 ounces of a silver for the base of the ring instead of 12/16 ounces, while still using 16/2 ounces to make the rest of the ring, how many total ounces of silver did the ring maker use then?

GPT-4o:

First, let's simplify the fractions and perform the necessary calculations.

1. The amount of silver used for the base of the ring is given as \( \frac{10}{16} \) ounces. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
   \[
   \frac{10}{16} = \frac{10 \div 2}{16 \div 2} = \frac{5}{8} \text{ ounces}
   \]

2. The amount of silver used for the rest of the ring is given as \( \frac{16}{2} \) ounces. We can simplify this fraction by performing the division:
   \[
   \frac{16}{2} = 8 \text{ ounces}
   \]

3. To find the total amount of silver used, we add the two amounts together:
   \[
   \frac{5}{8} \text{ ounces} + 8 \text{ ounces}
   \]

4. To add these, we can convert \( 8 \) ounces to a fraction with a common denominator of 8:
   \[
   8 = \frac{8 \times 8}{1 \times 8} = \frac{64}{8}
   \]

5. Now, we add the fractions:
   \[
   \frac{5}{8} + \frac{64}{8} = \frac{5 + 64}{8} = \frac{69}{8} \text{ ounces}
   \]

6. Converting \( \frac{69}{8} \) to a mixed number:
   \[
   \frac{69}{8} = 8 \frac{5}{8} \text{ ounces}
   \]

### Answer: 8 \(\frac{5}{8}\) ounces

🔗 Problem

Problem: A farmer has an apple tree that produced 10/11 bushels of apples in the morning and 17/11 bushels in the afternoon. How many bushels of apples did the tree produce in total?

GPT-4o:

To find the total number of bushels of apples produced by the tree, we need to add the bushels produced in the morning and the afternoon.

The tree produced \( \frac{10}{11} \) bushels in the morning and \( \frac{17}{11} \) bushels in the afternoon.

First, we add the fractions:
\[
\frac{10}{11} + \frac{17}{11}
\]

Since the denominators are the same, we can add the numerators directly:
\[
\frac{10 + 17}{11} = \frac{27}{11}
\]

Thus, the tree produced \( \frac{27}{11} \) bushels of apples in total.

### Answer: \(\frac{27}{11}\) bushels

Problem: Now assume the farmer's first apple tree produced 10/9 bushels instead of 10/11 bushels in the morning. With the same amount of apples in the afternoon, how many bushels of apples did this tree produce in one day?

GPT-4o:

To find the total number of bushels of apples produced by the tree in one day, we need to add the bushels produced in the morning and the afternoon.

The tree produced \( \frac{10}{9} \) bushels in the morning and \( \frac{17}{11} \) bushels in the afternoon.

To add these fractions, we need a common denominator. The least common multiple (LCM) of 9 and 11 is 99.

Convert each fraction to have the common denominator of 99:
\[
\frac{10}{9} = \frac{10 \times 11}{9 \times 11} = \frac{110}{99}
\]
\[
\frac{17}{11} = \frac{17 \times 9}{11 \times 9} = \frac{153}{99}
\]

Now, add the fractions:
\[
\frac{110}{99} + \frac{153}{99} = \frac{110 + 153}{99} = \frac{263}{99}
\]

Thus, the tree produced \( \frac{263}{99} \) bushels of apples in one day.

### Answer: \(\frac{263}{99}\) bushels

Problem: If Sam's binoculars increase his range of sight by 3/14 of a mile and Joe's binoculars increase his range of sight by exactly 1 mile (16/16), what is their combined range increase when they use the binoculars one after the other?

GPT-4o:

To find the combined range increase when Sam and Joe use their binoculars one after the other, we need to add the range increases provided by each of their binoculars.

Sam's binoculars increase his range of sight by \( \frac{3}{14} \) of a mile.
Joe's binoculars increase his range of sight by 1 mile, which can be expressed as \( \frac{16}{16} \) of a mile.

First, we need to add these two fractions:
\[ \frac{3}{14} + \frac{16}{16} \]

To add these fractions, we need a common denominator. The least common multiple of 14 and 16 is 112. We convert each fraction to have this common denominator:

\[ \frac{3}{14} = \frac{3 \times 8}{14 \times 8} = \frac{24}{112} \]
\[ \frac{16}{16} = \frac{16 \times 7}{16 \times 7} = \frac{112}{112} \]

Now, we add the fractions:
\[ \frac{24}{112} + \frac{112}{112} = \frac{24 + 112}{112} = \frac{136}{112} \]

We can simplify this fraction by dividing the numerator and the denominator by their greatest common divisor, which is 8:
\[ \frac{136 \div 8}{112 \div 8} = \frac{17}{14} \]

Thus, the combined range increase when Sam and Joe use their binoculars one after the other is \( \frac{17}{14} \) miles.

Problem: If Sam's binoculars instead increased his range of sight by 4/14 of a mile, while Joe's binoculars still increase his range of sight by exactly 1 mile, how much would their combined range increase be when they use the binoculars one after the other?

GPT-4o:

To find the combined range increase when Sam and Joe use their binoculars one after the other, we need to add the range increases provided by each of their binoculars.

Sam's binoculars now increase his range of sight by \( \frac{4}{14} \) of a mile.
Joe's binoculars increase his range of sight by 1 mile, which can be expressed as \( \frac{16}{16} \) of a mile.

First, we need to add these two fractions:
\[ \frac{4}{14} + \frac{16}{16} \]

To add these fractions, we need a common denominator. The least common multiple of 14 and 16 is 112. We convert each fraction to have this common denominator:

\[ \frac{4}{14} = \frac{4 \times 8}{14 \times 8} = \frac{32}{112} \]
\[ \frac{16}{16} = \frac{16 \times 7}{16 \times 7} = \frac{112}{112} \]

Now, we add the fractions:
\[ \frac{32}{112} + \frac{112}{112} = \frac{32 + 112}{112} = \frac{144}{112} \]

We can simplify this fraction by dividing the numerator and the denominator by their greatest common divisor, which is 16:
\[ \frac{144 \div 16}{112 \div 16} = \frac{9}{7} \]

Thus, the combined range increase when Sam and Joe use their binoculars one after the other is \( \frac{9}{7} \) miles.

Problem: Maria uses 15/10 yards of fabric for a section of a blanket and 9/18 more yards for another section. What is the total length of fabric Maria uses for these two sections?

GPT-4o:

First, we need to simplify the fractions to make the calculations easier.

For the first fraction:
\[ \frac{15}{10} = \frac{15 \div 5}{10 \div 5} = \frac{3}{2} \]

For the second fraction:
\[ \frac{9}{18} = \frac{9 \div 9}{18 \div 9} = \frac{1}{2} \]

Now, we add the two simplified fractions:
\[ \frac{3}{2} + \frac{1}{2} \]

Since the denominators are the same, we can add the numerators directly:
\[ \frac{3 + 1}{2} = \frac{4}{2} = 2 \]

### Answer: 2 yards

Problem: After reviewing her measurements, Maria realizes that she actually used a smaller piece of fabric for the second section of the blanket. Instead of the 9/18 yards she originally thought, she actually used only 6/18 yards of fabric. What is the total length of fabric that Maria used for these two sections of the blanket now?

GPT-4o:

First, we need to simplify the fractions to make the calculations easier.

For the first fraction:
\[ \frac{15}{10} = \frac{15 \div 5}{10 \div 5} = \frac{3}{2} \]

For the second fraction:
\[ \frac{6}{18} = \frac{6 \div 6}{18 \div 6} = \frac{1}{3} \]

Now, we need to add the two fractions. To do this, we need a common denominator. The least common multiple of 2 and 3 is 6.

Convert \(\frac{3}{2}\) to a fraction with a denominator of 6:
\[ \frac{3}{2} = \frac{3 \times 3}{2 \times 3} = \frac{9}{6} \]

Convert \(\frac{1}{3}\) to a fraction with a denominator of 6:
\[ \frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2}{6} \]

Now, add the two fractions:
\[ \frac{9}{6} + \frac{2}{6} = \frac{9 + 2}{6} = \frac{11}{6} \]

So, the total length of fabric Maria used for these two sections is:
\[ \frac{11}{6} \] yards, which can also be expressed as \(1 \frac{5}{6}\) yards.

### Answer: \(\frac{11}{6}\) yards or \(1 \frac{5}{6}\) yards

Problem: A turtle walks 10/5 miles forward, then walks backward 5/16 mile. How many miles has the turtle actually covered from its starting point?

GPT-4o:

First, let's determine the distance the turtle walked forward. The turtle walked:

\[ \frac{10}{5} = 2 \text{ miles forward} \]

Next, the turtle walked backward:

\[ \frac{5}{16} \text{ miles backward} \]

To find the net distance from the starting point, we subtract the backward distance from the forward distance:

\[ 2 - \frac{5}{16} \]

To perform this subtraction, we need a common denominator. The common denominator for 2 and \(\frac{5}{16}\) is 16. We can express 2 as a fraction with a denominator of 16:

\[ 2 = \frac{32}{16} \]

Now, we subtract the fractions:

\[ \frac{32}{16} - \frac{5}{16} = \frac{32 - 5}{16} = \frac{27}{16} \]

So, the turtle has actually covered:

\[ \frac{27}{16} \text{ miles from its starting point} \]

GPT-4o:

First, let's determine the distance the turtle walked forward. The turtle walked:

\[ \frac{10}{5} = 2 \text{ miles forward} \]

Next, the turtle walked backward:

\[ \frac{5}{6} \text{ miles backward} \]

To find the net distance from the starting point, we subtract the backward distance from the forward distance:

\[ 2 - \frac{5}{6} \]

To perform this subtraction, we need a common denominator. The common denominator for 2 and \(\frac{5}{6}\) is 6. We can express 2 as a fraction with a denominator of 6:

\[ 2 = \frac{12}{6} \]

Now, we subtract the fractions:

\[ \frac{12}{6} - \frac{5}{6} = \frac{12 - 5}{6} = \frac{7}{6} \]

Problem: A painter uses 18/11 liters of blue paint and 1/8 liters of white paint to mix a shade of sky blue. How much paint in liters did he use in total?

GPT-4o:

To find the total amount of paint used, we need to add the quantities of blue paint and white paint together.

First, let's write down the quantities:
- Blue paint: \( \frac{18}{11} \) liters
- White paint: \( \frac{1}{8} \) liters

To add these fractions, we need a common denominator. The least common multiple (LCM) of 11 and 8 is 88.

Next, we convert each fraction to have the common denominator of 88:
- Blue paint: \( \frac{18}{11} = \frac{18 \times 8}{11 \times 8} = \frac{144}{88} \)
- White paint: \( \frac{1}{8} = \frac{1 \times 11}{8 \times 11} = \frac{11}{88} \)

Now, we add the two fractions:
\[ \frac{144}{88} + \frac{11}{88} = \frac{144 + 11}{88} = \frac{155}{88} \]

Thus, the total amount of paint used is \( \frac{155}{88} \) liters.

Problem: After mixing the sky blue paint, the painter decides to mix in an additional 12/13 liters of white paint to lighten the shade. How many liters of paint does he have now in total?

GPT-4o:

To find the new total amount of paint, we need to add the additional \( \frac{12}{13} \) liters of white paint to the previous total of \( \frac{155}{88} \) liters.

First, let's write down the quantities:
- Previous total paint: \( \frac{155}{88} \) liters
- Additional white paint: \( \frac{12}{13} \) liters

To add these fractions, we need a common denominator. The least common multiple (LCM) of 88 and 13 is 1144.

Next, we convert each fraction to have the common denominator of 1144:
- Previous total paint: \( \frac{155}{88} = \frac{155 \times 13}{88 \times 13} = \frac{2015}{1144} \)
- Additional white paint: \( \frac{12}{13} = \frac{12 \times 88}{13 \times 88} = \frac{1056}{1144} \)

Now, we add the two fractions:
\[ \frac{2015}{1144} + \frac{1056}{1144} = \frac{2015 + 1056}{1144} = \frac{3071}{1144} \]

Thus, the new total amount of paint is \( \frac{3071}{1144} \) liters.

GPT-4o:

To find the total amount of paint used with the new quantity of white paint, we need to add the quantities of blue paint and white paint together.

First, let's write down the quantities:
- Blue paint: \( \frac{18}{11} \) liters
- White paint: \( \frac{1}{7} \) liters

To add these fractions, we need a common denominator. The least common multiple (LCM) of 11 and 7 is 77.

Next, we convert each fraction to have the common denominator of 77:
- Blue paint: \( \frac{18}{11} = \frac{18 \times 7}{11 \times 7} = \frac{126}{77} \)
- White paint: \( \frac{1}{7} = \frac{1 \times 11}{7 \times 11} = \frac{11}{77} \)

Now, we add the two fractions:
\[ \frac{126}{77} + \frac{11}{77} = \frac{126 + 11}{77} = \frac{137}{77} \]

Thus, the total amount of paint used is \( \frac{137}{77} \) liters.

Problem: At the end of a rainbow, there are pots filled with magical gold coins. One pot contains 12/13 of a pound of gold coins while another contains 3/2 pounds of gold coins. How much gold is there in total?

GPT-4o:

To find the total amount of gold in the two pots, we need to add the fractions representing the weights of the gold coins.

First, let's write down the fractions:
- The first pot contains \( \frac{12}{13} \) pounds of gold.
- The second pot contains \( \frac{3}{2} \) pounds of gold.

To add these fractions, we need a common denominator. The denominators are 13 and 2. The least common multiple (LCM) of 13 and 2 is 26.

Next, we convert each fraction to have the common denominator of 26:
- For \( \frac{12}{13} \):
  \[
  \frac{12}{13} = \frac{12 \times 2}{13 \times 2} = \frac{24}{26}
  \]

- For \( \frac{3}{2} \):
  \[
  \frac{3}{2} = \frac{3 \times 13}{2 \times 13} = \frac{39}{26}
  \]

Now, we add the two fractions:
\[
\frac{24}{26} + \frac{39}{26} = \frac{24 + 39}{26} = \frac{63}{26}
\]

The fraction \( \frac{63}{26} \) can be simplified to a mixed number:
\[
\frac{63}{26} = 2 \frac{11}{26}

GPT-4o:

To find the total amount of gold in the two pots, we need to add the fractions representing the weights of the gold coins.

First, let's write down the fractions:
- The first pot contains \( \frac{17}{13} \) pounds of gold.
- The second pot contains \( \frac{3}{2} \) pounds of gold.

To add these fractions, we need a common denominator. The denominators are 13 and 2. The least common multiple (LCM) of 13 and 2 is 26.

Next, we convert each fraction to have the common denominator of 26:

  \]

- For \( \frac{3}{2} \):
  \[
  \frac{3}{2} = \frac{3 \times 13}{2 \times 13} = \frac{39}{26}
  \]

Now, we add the two fractions:
\[

Problem: After watching the original message, Zorg receives an additional part of the message from earth that is 7/8 hours long. What is the total length of all parts of the message that Zorg received?

GPT-4o:

To find the total length of all parts of the message that Zorg received, we need to add the length of the additional part to the total length of the original message.

From the previous calculation, we know that the original message is 12 hours long.

The additional part of the message is \( \frac{7}{8} \) hours long.

Now, we add these two lengths together:
\[ 12 \text{ hours} + \frac{7}{8} \text{ hours} \]

To add these, we can convert 12 hours to a fraction with a common denominator of 8:
\[ 12 = \frac{96}{8} \]

Now, we add the fractions:
\[ \frac{96}{8} + \frac{7}{8} = \frac{96 + 7}{8} = \frac{103}{8} \]

To convert \( \frac{103}{8} \) back to a mixed number:

The first part of the message is \( \frac{4}{8} \) hours long. Simplifying this fraction, we get:
\[ \frac{4}{8} = \frac{1}{2} \text{ hour} \]

The second part of the message is \( \frac{11}{1} \) hours long. Simplifying this fraction, we get:
\[ \frac{11}{1} = 11 \text{ hours} \]

To find the total length of the message, we add the lengths of the two parts together:
\[ \frac{1}{2} \text{ hour} + 11 \text{ hours} \]

To add these, we can convert \( \frac{1}{2} \) hour to a decimal:
\[ \frac{1}{2} = 0.5 \text{ hour} \]

Now, adding the two parts together:
\[ 0.5 \text{ hour} + 11 \text{ hours} = 11.5 \text{ hours} \]

Problem: In a park, 10 ducks are equally distributed among 5 ponds, implying each pond has 10 / 5 ducks. In the same park, 8 fish are distributed among 10 small pools, with each pool having 8 / 10 fish. How many animals are there in each pond and pool combined?

GPT-4o:

First, let's determine the number of ducks in each pond. There are 10 ducks distributed equally among 5 ponds:

\[
\frac{10 \text{ ducks}}{5 \text{ ponds}} = 2 \text{ ducks per pond}
\]

Next, let's determine the number of fish in each pool. There are 8 fish distributed equally among 10 pools:

\[
\frac{8 \text{ fish}}{10 \text{ pools}} = 0.8 \text{ fish per pool}
\]

Now, we need to find the total number of animals in each pond and pool combined. Each pond has 2 ducks, and each pool has 0.8 fish:

\[
2 \text{ ducks} + 0.8 \text{ fish} = 2.8 \text{ animals}
\]

Problem: In the same park, there are also 12 frogs evenly distributed across 4 lily pads, meaning each lily pad has 12 / 4 frogs. Adding this to the previous sum of animals in each pond and pool, what is the total number of animals on each respective setting (pond, pool, lily pad) combined?

GPT-4o:

First, let's determine the number of frogs on each lily pad. There are 12 frogs distributed equally among 4 lily pads:

\[
\frac{12 \text{ frogs}}{4 \text{ lily pads}} = 3 \text{ frogs per lily pad}
\]

From the previous calculation, we know that each pond and pool combined has:

\[
2 \text{ ducks} + 0.8 \text{ fish} = 2.8 \text{ animals}
\]

Now, we add the number of frogs per lily pad to this sum:

\[
2.8 \text{ animals} + 3 \text{ frogs} = 5.8 \text{ animals}
\]

Problem: In the same park, let's consider a different scenario. Suppose there are now only 2 ducks equally distributed among 5 ponds. Given that each pond will have 2 / 5 ducks and each small pool still has 8 / 10 fish, what will be the total number of animals across each pond and pool in this new scenario?

GPT-4o:

First, let's determine the number of ducks in each pond. There are 2 ducks distributed equally among 5 ponds:

\[
\frac{2 \text{ ducks}}{5 \text{ ponds}} = 0.4 \text{ ducks per pond}
\]

Next, let's determine the number of fish in each pool. There are 8 fish distributed equally among 10 pools:

\[
\frac{8 \text{ fish}}{10 \text{ pools}} = 0.8 \text{ fish per pool}
\]

Now, we need to find the total number of animals in each pond and pool combined. Each pond has 0.4 ducks, and each pool has 0.8 fish:

\[

Problem: On a map, 15/11 inches represents the distance between Town A and Town B, and 16/15 inches represents the distance between Town B and Town C. What is the total distance between Town A and Town C on the map?

GPT-4o:

To find the total distance between Town A and Town C on the map, we need to add the distances between Town A and Town B, and Town B and Town C.

The distance between Town A and Town B is given as \( \frac{15}{11} \) inches.
The distance between Town B and Town C is given as \( \frac{16}{15} \) inches.

First, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 11 and 15 is 165.

Convert each fraction to have the common denominator of 165:

\[
\frac{15}{11} = \frac{15 \times 15}{11 \times 15} = \frac{225}{165}
\]

\[
\frac{16}{15} = \frac{16 \times 11}{15 \times 11} = \frac{176}{165}
\]

Now, add the two fractions:

\[
\frac{225}{165} + \frac{176}{165} = \frac{225 + 176}{165} = \frac{401}{165}
\]

Thus, the total distance between Town A and Town C on the map is \( \frac{401}{165} \) inches.

### Answer: \(\frac{401}{165}\) inches

Problem: On a map, 15/11 inches represents the distance between Town A and Town B, and 16/15 inches represents the distance between Town B and Town C. After measuring the distance between Town C and Town D, which was found to be 20/5 inches. What is the total distance between Town A and Town D on the map?

GPT-4o:

To find the total distance between Town A and Town D on the map, we need to add the distances between Town A and Town B, Town B and Town C, and Town C and Town D.

The distances are given as follows:
- Town A to Town B: \( \frac{15}{11} \) inches
- Town B to Town C: \( \frac{16}{15} \) inches
- Town C to Town D: \( \frac{20}{5} \) inches

First, simplify the distance between Town C and Town D:
\[
\frac{20}{5} = 4 \text{ inches}
\]

Next, we need to add these distances together. To do this, we need a common denominator for the fractions \( \frac{15}{11} \) and \( \frac{16}{15} \). The least common multiple (LCM) of 11 and 15 is 165.

Convert each fraction to have the common denominator of 165:

\[
\frac{15}{11} = \frac{15 \times 15}{11 \times 15} = \frac{225}{165}
\]

\[
\frac{16}{15} = \frac{16 \times 11}{15 \times 11} = \frac{176}{165}
\]

Now, add the two fractions:

\[
\frac{225}{165} + \frac{176}{165} = \frac{225 + 176}{165} = \frac{401}{165}
\]

Next, convert the whole number 4 to a fraction with the same denominator:

\[
4 = \frac{4 \times 165}{1 \times 165} = \frac{660}{165}
\]

Now, add this to the previous sum:

\[
\frac{401}{165} + \frac{660}{165} = \frac{401 + 660}{165} = \frac{1061}{165}
\]

Thus, the total distance between Town A and Town D on the map is \( \frac{1061}{165} \) inches.

GPT-4o:

To find the total distance between Town A and Town C on the map, we need to add the distances between Town A and Town B, and Town B and Town C.

The distance between Town A and Town B is given as \( \frac{15}{11} \) inches.
The distance between Town B and Town C is given as \( \frac{16}{7} \) inches.

First, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 11 and 7 is 77.

Convert each fraction to have the common denominator of 77:

\[
\frac{15}{11} = \frac{15 \times 7}{11 \times 7} = \frac{105}{77}
\]

\[
\frac{16}{7} = \frac{16 \times 11}{7 \times 11} = \frac{176}{77}
\]

Now, add the two fractions:

\[
\frac{105}{77} + \frac{176}{77} = \frac{105 + 176}{77} = \frac{281}{77}
\]

Thus, the total distance between Town A and Town C on the map is \( \frac{281}{77} \) inches.

### Answer: \(\frac{281}{77}\) inches

🔗 Problem

Problem: A soap company produces 13/18 tons of Soap A and 4/6 tons of Soap B in a day. How many tons of soap do they produce in total each day?

GPT-4o:

To find the total amount of soap produced each day, we need to add the amounts of Soap A and Soap B.

First, let's simplify the fraction for Soap B:
\[ \frac{4}{6} = \frac{2}{3} \]

Now, we need to add the two fractions:
\[ \frac{13}{18} + \frac{2}{3} \]

To add these fractions, we need a common denominator. The least common multiple of 18 and 3 is 18. We can convert \(\frac{2}{3}\) to a fraction with a denominator of 18:
\[ \frac{2}{3} = \frac{2 \times 6}{3 \times 6} = \frac{12}{18} \]

Now we can add the fractions:
\[ \frac{13}{18} + \frac{12}{18} = \frac{13 + 12}{18} = \frac{25}{18} \]

So, the total amount of soap produced each day is:
\[ \frac{25}{18} \text{ tons} \]

### Answer: \(\frac{25}{18}\) tons

Correct? Yes

🔗 Follow-up

Problem: The soap company plans to double their daily production. After producing 13/18 tons of Soap A and 4/6 tons of Soap B each day, how many tons of soap will they produce in total when they double their production?

GPT-4o:

First, let's determine the current total daily production of soap.

We already know from the previous problem that:
\[ \frac{13}{18} \text{ tons of Soap A} + \frac{4}{6} \text{ tons of Soap B} \]

We simplified \(\frac{4}{6}\) to \(\frac{2}{3}\), and then found a common denominator to add the fractions:
\[ \frac{13}{18} + \frac{2}{3} = \frac{13}{18} + \frac{12}{18} = \frac{25}{18} \text{ tons} \]

Now, if the company plans to double their daily production, we need to multiply the total amount by 2:
\[ 2 \times \frac{25}{18} = \frac{2 \times 25}{18} = \frac{50}{18} \]

We can simplify \(\frac{50}{18}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
\[ \frac{50 \div 2}{18 \div 2} = \frac{25}{9} \]

So, when the company doubles their production, they will produce:
\[ \frac{25}{9} \text{ tons of soap} \]

### Answer: \(\frac{25}{9}\) tons

Expected answer: 25/9

Correct? Yes

To find the total amount of soap produced each day after the change, we need to add the new amount of Soap A and the amount of Soap B.

First, let's simplify the fraction for Soap B:
\[ \frac{4}{6} = \frac{2}{3} \]

Now, we need to add the two fractions:
\[ \frac{17}{18} + \frac{2}{3} \]

To add these fractions, we need a common denominator. The least common multiple of 18 and 3 is 18. We can convert \(\frac{2}{3}\) to a fraction with a denominator of 18:
\[ \frac{2}{3} = \frac{2 \times 6}{3 \times 6} = \frac{12}{18} \]

Now we can add the fractions:
\[ \frac{17}{18} + \frac{12}{18} = \frac{17 + 12}{18} = \frac{29}{18} \]

So, the total amount of soap produced each day after the change is:
\[ \frac{29}{18} \text{ tons} \]

### Answer: \(\frac{29}{18}\) tons

Problem: Mark bought a sleeping bag that was 19/2 feet long. However, he decides to cut off 13/12 feet from it to fit his height. How long is his sleeping bag now?

GPT-4o:

To determine the new length of Mark's sleeping bag, we need to subtract the length he cut off from the original length.

1. The original length of the sleeping bag is \( \frac{19}{2} \) feet.
2. The length he cut off is \( \frac{13}{12} \) feet.

First, we need to find a common denominator to subtract these fractions. The least common multiple of 2 and 12 is 12.

Convert \( \frac{19}{2} \) to a fraction with a denominator of 12:
\[ \frac{19}{2} = \frac{19 \times 6}{2 \times 6} = \frac{114}{12} \]

Now, subtract \( \frac{13}{12} \) from \( \frac{114}{12} \):
\[ \frac{114}{12} - \frac{13}{12} = \frac{114 - 13}{12} = \frac{101}{12} \]

So, the new length of the sleeping bag is \( \frac{101}{12} \) feet.

GPT-4o:

To determine the new length of Mark's sleeping bag after the additional cut, we need to subtract \( \frac{13}{14} \) feet from the current length of \( \frac{101}{12} \) feet.

First, we need to find a common denominator for the fractions \( \frac{101}{12} \) and \( \frac{13}{14} \). The least common multiple of 12 and 14 is 84.

Convert \( \frac{101}{12} \) to a fraction with a denominator of 84:
\[ \frac{101}{12} = \frac{101 \times 7}{12 \times 7} = \frac{707}{84} \]

Convert \( \frac{13}{14} \) to a fraction with a denominator of 84:
\[ \frac{13}{14} = \frac{13 \times 6}{14 \times 6} = \frac{78}{84} \]

Now, subtract \( \frac{78}{84} \) from \( \frac{707}{84} \):
\[ \frac{707}{84} - \frac{78}{84} = \frac{707 - 78}{84} = \frac{629}{84} \]

So, the new length of the sleeping bag is \( \frac{629}{84} \) feet.

First, we need to simplify the fractions if possible.

For the monkeys:
\[ \frac{6}{20} \]
We can simplify this fraction by finding the greatest common divisor (GCD) of 6 and 20, which is 2.
\[ \frac{6 \div 2}{20 \div 2} = \frac{3}{10} \]

For the giraffes:
\[ \frac{18}{15} \]
We can simplify this fraction by finding the GCD of 18 and 15, which is 3.
\[ \frac{18 \div 3}{15 \div 3} = \frac{6}{5} \]

Next, we need to add the two fractions together. To do this, we need a common denominator. The least common multiple (LCM) of 10 and 5 is 10.

Problem: A jeweler has 5/14 pound of silver and adds 18/19 pounds more to the supply. How many pounds of silver does the jeweler have now to make rings?

GPT-4o:

To find the total amount of silver the jeweler has, we need to add the two fractions: \( \frac{5}{14} \) and \( \frac{18}{19} \).

First, we need a common denominator to add these fractions. The least common multiple (LCM) of 14 and 19 is 266.

Next, we convert each fraction to have this common denominator:
\[ \frac{5}{14} = \frac{5 \times 19}{14 \times 19} = \frac{95}{266} \]
\[ \frac{18}{19} = \frac{18 \times 14}{19 \times 14} = \frac{252}{266} \]

Now, we add the two fractions:
\[ \frac{95}{266} + \frac{252}{266} = \frac{95 + 252}{266} = \frac{347}{266} \]

Since \( \frac{347}{266} \) is an improper fraction, we can convert it to a mixed number if needed. However, in this context, the improper fraction is sufficient to represent the total amount of silver.

First, we need a common denominator for these fractions. The least common multiple (LCM) of 266 and 17 is 4522.

Next, we convert each fraction to have this common denominator:
\[ \frac{347}{266} = \frac{347 \times 17}{266 \times 17} = \frac{5899}{4522} \]
\[ \frac{2}{17} = \frac{2 \times 266}{17 \times 266} = \frac{532}{4522} \]

Now, we add the two fractions:
\[ \frac{5899}{4522} + \frac{532}{4522} = \frac{5899 + 532}{4522} = \frac{6431}{4522} \]

Since \( \frac{6431}{4522} \) is an improper fraction, we can convert it to a mixed number if needed. However, in this context, the improper fraction is sufficient to represent the total amount of silver.

To find the total amount of silver the jeweler has, we need to add the two fractions: \( \frac{8}{14} \) and \( \frac{18}{19} \).

First, we simplify \( \frac{8}{14} \):
\[ \frac{8}{14} = \frac{4}{7} \]

Next, we need a common denominator to add \( \frac{4}{7} \) and \( \frac{18}{19} \). The least common multiple (LCM) of 7 and 19 is 133.

We convert each fraction to have this common denominator:
\[ \frac{4}{7} = \frac{4 \times 19}{7 \times 19} = \frac{76}{133} \]
\[ \frac{18}{19} = \frac{18 \times 7}{19 \times 7} = \frac{126}{133} \]

Now, we add the two fractions:
\[ \frac{76}{133} + \frac{126}{133} = \frac{76 + 126}{133} = \frac{202}{133} \]

Since \( \frac{202}{133} \) is an improper fraction, we can convert it to a mixed number if needed. However, in this context, the improper fraction is sufficient to represent the total amount of silver.

Problem: A turtle starts at a point and moves 11 meters northward. Then, it moves 15/15 of a meter back towards the starting point. How many meters is the turtle from its starting point after these two movement?

GPT-4o:

First, let's determine the total distance the turtle moves northward. The turtle moves 11 meters northward.

Next, the turtle moves 15/15 of a meter back towards the starting point. Since 15/15 is equivalent to 1, the turtle moves 1 meter back.

To find the turtle's final position relative to the starting point, we subtract the distance it moved back from the distance it moved northward:
\[ 11 \text{ meters} - 1 \text{ meter} = 10 \text{ meters} \]

Thus, the turtle is 10 meters from its starting point after these two movements.

### Answer: 10 meters

Problem: Reconsider the previous scenario, but this time the turtle returns 15/8 of a meter back towards the starting point instead of the former 15/15 meters. Now, how many meters is the turtle from its starting point after these two movements?

GPT-4o:

First, let's determine the total distance the turtle moves northward. The turtle moves 11 meters northward.

Next, the turtle moves 15/8 of a meter back towards the starting point. 

To find the turtle's final position relative to the starting point, we subtract the distance it moved back from the distance it moved northward:
\[ 11 \text{ meters} - \frac{15}{8} \text{ meters} \]

First, convert 11 meters to a fraction with a common denominator of 8:
\[ 11 = \frac{88}{8} \]

Now, perform the subtraction:
\[ \frac{88}{8} - \frac{15}{8} = \frac{88 - 15}{8} = \frac{73}{8} \]

To convert \(\frac{73}{8}\) back to a decimal or mixed number:
\[ \frac{73}{8} = 9.125 \]

Thus, the turtle is 9.125 meters from its starting point after these two movements.

### Answer: 9.125 meters

Problem: Chloe has a chocolate bar that is 19/2 ounces. If she eats a piece that is 17/2 ounces, how many ounces of chocolate does she have left?

GPT-4o:

To determine how many ounces of chocolate Chloe has left, we need to subtract the amount she ate from the total amount she initially had.

Chloe's initial amount of chocolate is \( \frac{19}{2} \) ounces.
The amount she ate is \( \frac{17}{2} \) ounces.

We perform the subtraction:
\[
\frac{19}{2} - \frac{17}{2} = \frac{19 - 17}{2} = \frac{2}{2} = 1 \text{ ounce}
\]

### Answer: 1 ounce

Problem: After Chloe eats a piece of the chocolate bar, she decides to add a piece from another chocolate bar. The piece from the other bar weighs 4/14 ounces. How many ounces of chocolate does Chloe have now?

GPT-4o:

First, we need to determine how much chocolate Chloe had left after eating the initial piece. From the previous calculation, we know she had 1 ounce left.

Next, we add the piece from the other chocolate bar, which weighs \( \frac{4}{14} \) ounces. To add these amounts, we need a common denominator. The common denominator for 1 and \( \frac{4}{14} \) is 14.

Convert 1 ounce to a fraction with a denominator of 14:
\[
1 = \frac{14}{14}
\]

Now, add \( \frac{14}{14} \) and \( \frac{4}{14} \):
\[
\frac{14}{14} + \frac{4}{14} = \frac{14 + 4}{14} = \frac{18}{14}
\]

Simplify \( \frac{18}{14} \):
\[
\frac{18}{14} = \frac{9}{7}
\]

So, Chloe now has \( \frac{9}{7} \) ounces of chocolate.

🔗 Problem

Problem: Sammy has a backpack with a capacity of 20/9 liters. If he adds another pouch to the backpack that can hold 8/4 more liters, what will be the total capacity of his backpack?

GPT-4o:

First, let's simplify the capacity of the additional pouch. The capacity of the pouch is given as \( \frac{8}{4} \) liters. Simplifying this fraction:

\[ \frac{8}{4} = 2 \]

So, the additional pouch can hold 2 liters.

Next, we need to add this capacity to the original capacity of the backpack, which is \( \frac{20}{9} \) liters. To find the total capacity, we add these two quantities:

\[ \frac{20}{9} + 2 \]

To add these, we need a common denominator. The number 2 can be written as a fraction with a denominator of 9:

\[ 2 = \frac{18}{9} \]

Now, we can add the two fractions:

\[ \frac{20}{9} + \frac{18}{9} = \frac{20 + 18}{9} = \frac{38}{9} \]

So, the total capacity of the backpack with the additional pouch is \( \frac{38}{9} \) liters.

### Answer: \(\frac{38}{9}\) liters

Correct? Yes

🔗 Follow-up

Problem: In addition to his already expanded backpack, Sammy finds another tiny side pocket that can carry an extra 3/8 of a liter. What is the total capacity of his backpack now?

GPT-4o:

To find the new total capacity of Sammy's backpack, we need to add the capacity of the tiny side pocket to the current total capacity of the backpack.

The current total capacity of the backpack is \( \frac{38}{9} \) liters, and the tiny side pocket can carry an additional \( \frac{3}{8} \) liters.

To add these two fractions, we need a common denominator. The least common multiple (LCM) of 9 and 8 is 72. We will convert both fractions to have this common denominator.

First, convert \( \frac{38}{9} \) to a fraction with a denominator of 72:

\[ \frac{38}{9} = \frac{38 \times 8}{9 \times 8} = \frac{304}{72} \]

Next, convert \( \frac{3}{8} \) to a fraction with a denominator of 72:

\[ \frac{3}{8} = \frac{3 \times 9}{8 \times 9} = \frac{27}{72} \]

Now, we can add the two fractions:

\[ \frac{304}{72} + \frac{27}{72} = \frac{304 + 27}{72} = \frac{331}{72} \]

So, the new total capacity of Sammy's backpack is \( \frac{331}{72} \) liters.

### Answer: \(\frac{331}{72}\) liters

Expected answer: 331/72

Correct? Yes

🔗 Follow-up

Problem: Instead of the backpack having an initial capacity of 20/9 liters, let's say it could only carry 20/12 liters. If Sammy still adds the same extra pouch of 8/4 liters, what would the total capacity of his backpack be then?

GPT-4o:

First, let's simplify the capacity of the additional pouch. The capacity of the pouch is given as \( \frac{8}{4} \) liters. Simplifying this fraction:

\[ \frac{8}{4} = 2 \]

So, the additional pouch can hold 2 liters.

Next, we need to add this capacity to the new initial capacity of the backpack, which is \( \frac{20}{12} \) liters. To simplify \( \frac{20}{12} \):

\[ \frac{20}{12} = \frac{5}{3} \]

Now, we add the simplified initial capacity to the capacity of the additional pouch:

\[ \frac{5}{3} + 2 \]

To add these, we need a common denominator. The number 2 can be written as a fraction with a denominator of 3:

\[ 2 = \frac{6}{3} \]

Now, we can add the two fractions:

\[ \frac{5}{3} + \frac{6}{3} = \frac{5 + 6}{3} = \frac{11}{3} \]

So, the total capacity of the backpack with the additional pouch is \( \frac{11}{3} \) liters.

### Answer: \(\frac{11}{3}\) liters

Problem: Captain Hook has 11/8 ounces of gold. He finds an additional 5/5 ounces of gold on his latest treasure hunt. What is the total weight of the gold Captain Hook now has?

GPT-4o:

To find the total weight of the gold Captain Hook now has, we need to add the two amounts of gold together.

First, let's convert the fractions to a common denominator if necessary. In this case, the denominators are already compatible for addition.

The fractions are:
\[ \frac{11}{8} \]
\[ \frac{5}{5} \]

Since \(\frac{5}{5}\) is equivalent to 1, we can rewrite the problem as:
\[ \frac{11}{8} + 1 \]

To add these, we need to express 1 as a fraction with a denominator of 8:
\[ 1 = \frac{8}{8} \]

Now we can add the fractions:
\[ \frac{11}{8} + \frac{8}{8} = \frac{11 + 8}{8} = \frac{19}{8} \]

So, the total weight of the gold Captain Hook now has is:
\[ \frac{19}{8} \] ounces.

### Answer: \(\frac{19}{8}\) ounces

Problem: After counting his newly found gold, Captain Hook discovers an additional 7/11 ounces of gold hidden in a small pouch he had forgotten about. What is the total weight of all the gold Captain Hook now has?

GPT-4o:

To find the total weight of all the gold Captain Hook now has, we need to add the newly discovered \(\frac{7}{11}\) ounces of gold to the previously calculated \(\frac{19}{8}\) ounces of gold.

First, we need to find a common denominator for the fractions \(\frac{19}{8}\) and \(\frac{7}{11}\). The least common multiple (LCM) of 8 and 11 is 88.

Next, we convert each fraction to have the common denominator of 88:

\[
\frac{19}{8} = \frac{19 \times 11}{8 \times 11} = \frac{209}{88}
\]

\[
\frac{7}{11} = \frac{7 \times 8}{11 \times 8} = \frac{56}{88}
\]

Now, we can add the two fractions:

\[
\frac{209}{88} + \frac{56}{88} = \frac{209 + 56}{88} = \frac{265}{88}
\]

So, the total weight of all the gold Captain Hook now has is:

GPT-4o:

To find the total weight of the gold Captain Hook would have had, we need to add the two amounts of gold together.

The fractions are:
\[ \frac{11}{8} \]
\[ \frac{7}{5} \]

To add these fractions, we need a common denominator. The least common multiple of 8 and 5 is 40.

Convert each fraction to have a denominator of 40:
\[ \frac{11}{8} = \frac{11 \times 5}{8 \times 5} = \frac{55}{40} \]
\[ \frac{7}{5} = \frac{7 \times 8}{5 \times 8} = \frac{56}{40} \]

Now, add the fractions:
\[ \frac{55}{40} + \frac{56}{40} = \frac{55 + 56}{40} = \frac{111}{40} \]

So, the total weight of the gold Captain Hook would have had is:

Problem: If Jake originally had 9/10 of a dollar and then received an additional 20/15 of a dollar, how much money does he have in his wallet now?

GPT-4o:

First, let's convert the fractions to a common denominator to make the addition easier. 

Jake originally had \( \frac{9}{10} \) of a dollar.

Next, we simplify the fraction \( \frac{20}{15} \):
\[ \frac{20}{15} = \frac{20 \div 5}{15 \div 5} = \frac{4}{3} \]

Now, we need to add \( \frac{9}{10} \) and \( \frac{4}{3} \). To do this, we find a common denominator. The least common multiple of 10 and 3 is 30.

Convert \( \frac{9}{10} \) to a fraction with a denominator of 30:
\[ \frac{9}{10} = \frac{9 \times 3}{10 \times 3} = \frac{27}{30} \]

Convert \( \frac{4}{3} \) to a fraction with a denominator of 30:
\[ \frac{4}{3} = \frac{4 \times 10}{3 \times 10} = \frac{40}{30} \]

Now, add the two fractions:
\[ \frac{27}{30} + \frac{40}{30} = \frac{27 + 40}{30} = \frac{67}{30} \]

Thus, Jake has \( \frac{67}{30} \) dollars in his wallet.

Now, Jake found an additional \( \frac{11}{5} \) of a dollar. To add these two amounts, we need a common denominator. The least common multiple of 30 and 5 is 30.

Convert \( \frac{11}{5} \) to a fraction with a denominator of 30:
\[ \frac{11}{5} = \frac{11 \times 6}{5 \times 6} = \frac{66}{30} \]

Now, add the two fractions:
\[ \frac{67}{30} + \frac{66}{30} = \frac{67 + 66}{30} = \frac{133}{30} \]

Thus, Jake now has \( \frac{133}{30} \) dollars in his wallet.

First, let's simplify the fractions involved.

Jake originally had \( \frac{9}{8} \) of a dollar.

Next, we simplify the fraction \( \frac{20}{15} \):
\[ \frac{20}{15} = \frac{20 \div 5}{15 \div 5} = \frac{4}{3} \]

Now, we need to add \( \frac{9}{8} \) and \( \frac{4}{3} \). To do this, we find a common denominator. The least common multiple of 8 and 3 is 24.

Convert \( \frac{9}{8} \) to a fraction with a denominator of 24:
\[ \frac{9}{8} = \frac{9 \times 3}{8 \times 3} = \frac{27}{24} \]

Convert \( \frac{4}{3} \) to a fraction with a denominator of 24:
\[ \frac{4}{3} = \frac{4 \times 8}{3 \times 8} = \frac{32}{24} \]

Now, add the two fractions:
\[ \frac{27}{24} + \frac{32}{24} = \frac{27 + 32}{24} = \frac{59}{24} \]

Problem: Paul has built the front half of a chair that measures 5/2 feet high. He also constructs the back portion of the chair that measures 20/14 feet. What is the combined height of the front and back portions of the chair that Paul has constructed?

GPT-4o:

To find the combined height of the front and back portions of the chair, we need to add the heights of both portions.

First, let's convert the fractions to have a common denominator. The fractions are \( \frac{5}{2} \) and \( \frac{20}{14} \).

The least common multiple (LCM) of 2 and 14 is 14. We will convert \( \frac{5}{2} \) to a fraction with a denominator of 14.

\[ \frac{5}{2} = \frac{5 \times 7}{2 \times 7} = \frac{35}{14} \]

Now, we add \( \frac{35}{14} \) and \( \frac{20}{14} \):

\[ \frac{35}{14} + \frac{20}{14} = \frac{35 + 20}{14} = \frac{55}{14} \]

So, the combined height of the front and back portions of the chair is \( \frac{55}{14} \) feet.

The combined height of the chair is \( \frac{55}{14} \) feet. First, let's convert 2 feet to a fraction with the same denominator (14) to make the subtraction easier.

\[ 2 = \frac{2 \times 14}{1 \times 14} = \frac{28}{14} \]

Now, we subtract \( \frac{28}{14} \) from \( \frac{55}{14} \):

\[ \frac{55}{14} - \frac{28}{14} = \frac{55 - 28}{14} = \frac{27}{14} \]

So, the new height of the chair is \( \frac{27}{14} \) feet.

🔗 Problem

Problem: John has 5 shirts and he donated 12/9 of them to charity. How many shirts does he have left?

GPT-4o:

First, let's simplify the fraction \( \frac{12}{9} \). We can do this by finding the greatest common divisor (GCD) of 12 and 9, which is 3.

\[
\frac{12}{9} = \frac{12 \div 3}{9 \div 3} = \frac{4}{3}
\]

Next, we need to determine how many shirts John donated. He originally had 5 shirts, and he donated \( \frac{4}{3} \) of them. To find out how many shirts this is, we multiply:

\[
5 \times \frac{4}{3} = \frac{5 \times 4}{3} = \frac{20}{3} \approx 6.67
\]

Since John cannot donate a fraction of a shirt, we need to consider that donating \( \frac{4}{3} \) of his shirts is not feasible. This suggests there might be an error in the problem's setup, as donating more shirts than he has is not possible.

However, if we assume the problem meant to donate a fraction of the shirts he has, we can interpret it as donating a part of each shirt, which is not practical in real life. Therefore, we should re-evaluate the problem's context or consider it as a theoretical exercise.

Given the context, if John donated \( \frac{4}{3} \) of his shirts, he would have:

\[
5 - \frac{20}{3} = 5 - 6.67 \approx -1.67
\]

Since this is not possible, we conclude that the problem might have an error. If we consider a more realistic scenario, John cannot donate more shirts than he has.

### Answer: The problem contains an error as John cannot donate more shirts than he has.

GPT-4o:

To find the length of Bob's jacket after the alteration, we need to subtract the length he cut off from the original length.

1. The original length of the jacket is \( \frac{14}{3} \) meters.
2. The length he cut off is \( \frac{14}{16} \) meters.

First, let's simplify \( \frac{14}{16} \):
\[ \frac{14}{16} = \frac{7}{8} \]

Now, we need to subtract \( \frac{7}{8} \) from \( \frac{14}{3} \). To do this, we need a common denominator. The least common multiple of 3 and 8 is 24.

Convert both fractions to have a denominator of 24:
\[ \frac{14}{3} = \frac{14 \times 8}{3 \times 8} = \frac{112}{24} \]
\[ \frac{7}{8} = \frac{7 \times 3}{8 \times 3} = \frac{21}{24} \]

Now, subtract the two fractions:
\[ \frac{112}{24} - \frac{21}{24} = \frac{112 - 21}{24} = \frac{91}{24} \]

So, the length of Bob's jacket after the alteration is \( \frac{91}{24} \) meters.

To find the remaining length of Bob's jacket after the additional alteration, we need to subtract \( \frac{9}{4} \) meters from the current length of \( \frac{91}{24} \) meters.

First, we need a common denominator to perform the subtraction. The least common multiple of 24 and 4 is 24.

Convert \( \frac{9}{4} \) to have a denominator of 24:
\[ \frac{9}{4} = \frac{9 \times 6}{4 \times 6} = \frac{54}{24} \]

Now, subtract \( \frac{54}{24} \) from \( \frac{91}{24} \):
\[ \frac{91}{24} - \frac{54}{24} = \frac{91 - 54}{24} = \frac{37}{24} \]

So, the remaining length of Bob's jacket after the additional alteration is \( \frac{37}{24} \) meters.

To find the new length of Bob's jacket after the alteration, we need to subtract the length he cut off from the new original length.

1. The new original length of the jacket is \( \frac{16}{3} \) meters.
2. The length he cut off is \( \frac{14}{16} \) meters, which simplifies to \( \frac{7}{8} \) meters.

First, let's convert both fractions to have a common denominator. The least common multiple of 3 and 8 is 24.

Convert both fractions to have a denominator of 24:
\[ \frac{16}{3} = \frac{16 \times 8}{3 \times 8} = \frac{128}{24} \]
\[ \frac{7}{8} = \frac{7 \times 3}{8 \times 3} = \frac{21}{24} \]

Now, subtract the two fractions:
\[ \frac{128}{24} - \frac{21}{24} = \frac{128 - 21}{24} = \frac{107}{24} \]

Problem: If John watched a movie for 10/12 of an hour and then watched a TV show for another 3/8 of an hour, and then repeated this same routine, what is the total time he spent watching in hours?

GPT-4o:

To find the total time John spent watching, we need to first determine the time for one complete routine and then double it since he repeated the routine.

First, simplify \( \frac{10}{12} \):
\[ \frac{10}{12} = \frac{5}{6} \]

Next, find a common denominator for \( \frac{5}{6} \) and \( \frac{3}{8} \). The least common multiple (LCM) of 6 and 8 is 24.

Convert \( \frac{5}{6} \) to a fraction with a denominator of 24:
\[ \frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24} \]

Convert \( \frac{3}{8} \) to a fraction with a denominator of 24:
\[ \frac{3}{8} = \frac{3 \times 3}{8 \times 3} = \frac{9}{24} \]

Now, add the two fractions for one routine:
\[ \frac{20}{24} + \frac{9}{24} = \frac{29}{24} \]

Since John repeated this routine, we need to double the time:
\[ 2 \times \frac{29}{24} = \frac{2 \times 29}{24} = \frac{58}{24} \]

Convert \( \frac{58}{24} \) to a mixed number:
\[ \frac{58}{24} = 2 \frac{10}{24} \]

Simplify \( \frac{10}{24} \):
\[ \frac{10}{24} = \frac{5}{12} \]

To find the total time John spent watching, we need to add the two fractions of hours together: \( \frac{10}{7} \) and \( \frac{3}{8} \).

First, find a common denominator for \( \frac{10}{7} \) and \( \frac{3}{8} \). The least common multiple (LCM) of 7 and 8 is 56.

Convert \( \frac{10}{7} \) to a fraction with a denominator of 56:
\[ \frac{10}{7} = \frac{10 \times 8}{7 \times 8} = \frac{80}{56} \]

Convert \( \frac{3}{8} \) to a fraction with a denominator of 56:
\[ \frac{3}{8} = \frac{3 \times 7}{8 \times 7} = \frac{21}{56} \]

Now, add the two fractions:
\[ \frac{80}{56} + \frac{21}{56} = \frac{80 + 21}{56} = \frac{101}{56} \]

Convert \( \frac{101}{56} \) to a mixed number:
\[ \frac{101}{56} = 1 \frac{45}{56} \]

Problem: Mr. Carpenter makes crafting chairs a meticulous process. He takes 5/3 hours to build the frame and additional 10/13 hours to upholster it. How long does it take for him to build a chair from start to finish?

GPT-4o:

To determine the total time Mr. Carpenter takes to build a chair from start to finish, we need to add the time he spends building the frame to the time he spends upholstering it.

First, let's convert the fractions to a common denominator to make the addition easier. The denominators are 3 and 13. The least common multiple (LCM) of 3 and 13 is 39.

Convert \( \frac{5}{3} \) to a fraction with a denominator of 39:
\[ \frac{5}{3} = \frac{5 \times 13}{3 \times 13} = \frac{65}{39} \]

Convert \( \frac{10}{13} \) to a fraction with a denominator of 39:
\[ \frac{10}{13} = \frac{10 \times 3}{13 \times 3} = \frac{30}{39} \]

Now, add the two fractions:
\[ \frac{65}{39} + \frac{30}{39} = \frac{65 + 30}{39} = \frac{95}{39} \]

To simplify \( \frac{95}{39} \), we can perform the division:
\[ 95 \div 39 \approx 2.435897 \]

Thus, the total time it takes for Mr. Carpenter to build a chair from start to finish is approximately \( \frac{95}{39} \) hours.

### Answer: \( \frac{95}{39} \) hours

Problem: Mr. Carpenter has now taken on an additional task. After building the chair and doing the upholstery work, he spends another 8/19 hours to apply the varnish. Now, how long does the entire process of making a chair take?

GPT-4o:

To determine the total time Mr. Carpenter takes to complete the entire process of making a chair, we need to add the time he spends building the frame, upholstering it, and applying the varnish.

From the previous calculation, we know that the time to build the frame and upholster it is \( \frac{95}{39} \) hours.

Now, we need to add the time to apply the varnish, which is \( \frac{8}{19} \) hours.

First, let's convert \( \frac{8}{19} \) to a fraction with a common denominator with \( \frac{95}{39} \). The least common multiple (LCM) of 39 and 19 is 741.

Convert \( \frac{95}{39} \) to a fraction with a denominator of 741:
\[ \frac{95}{39} = \frac{95 \times 19}{39 \times 19} = \frac{1805}{741} \]

Convert \( \frac{8}{19} \) to a fraction with a denominator of 741:
\[ \frac{8}{19} = \frac{8 \times 39}{19 \times 39} = \frac{312}{741} \]

Now, add the two fractions:
\[ \frac{1805}{741} + \frac{312}{741} = \frac{1805 + 312}{741} = \frac{2117}{741} \]

To simplify \( \frac{2117}{741} \), we can perform the division:
\[ 2117 \div 741 \approx 2.857 \]

Thus, the total time it takes for Mr. Carpenter to complete the entire process of making a chair is approximately \( \frac{2117}{741} \) hours.

### Answer: \( \frac{2117}{741} \) hours

Problem: In another batch of chair production, Mr. Carpenter managed to reduce his timeframe. Now, he takes only 5/10 hours to build the frame of the chair while the time for upholstery stays the same as 10/13 hours. How long does it take for him to build a chair with the new time for frame construction?

GPT-4o:

To determine the total time Mr. Carpenter takes to build a chair with the new time for frame construction, we need to add the time he spends building the frame to the time he spends upholstering it.

First, let's simplify the fraction for the new time to build the frame:
\[ \frac{5}{10} = \frac{1}{2} \]

Now, we need to add this time to the time he spends upholstering the chair, which is \( \frac{10}{13} \).

To add these fractions, we need a common denominator. The denominators are 2 and 13. The least common multiple (LCM) of 2 and 13 is 26.

Convert \( \frac{1}{2} \) to a fraction with a denominator of 26:
\[ \frac{1}{2} = \frac{1 \times 13}{2 \times 13} = \frac{13}{26} \]

Convert \( \frac{10}{13} \) to a fraction with a denominator of 26:
\[ \frac{10}{13} = \frac{10 \times 2}{13 \times 2} = \frac{20}{26} \]

Now, add the two fractions:
\[ \frac{13}{26} + \frac{20}{26} = \frac{13 + 20}{26} = \frac{33}{26} \]

To simplify \( \frac{33}{26} \), we can perform the division:
\[ 33 \div 26 \approx 1.26923077 \]

Thus, the total time it takes for Mr. Carpenter to build a chair with the new time for frame construction is \( \frac{33}{26} \) hours.

GPT-4o:

First, let's determine the diameter of the small bead. The small bead has a diameter of \( \frac{8}{4} \) mm.

\[
\frac{8}{4} = 2 \text{ mm}
\]

Next, let's determine the diameter of the large bead. The large bead has a diameter of \( \frac{15}{2} \) mm.

\[
\frac{15}{2} = 7.5 \text{ mm}
\]

Now, we add the diameters of the small and large beads to find the total added diameter.

\[
2 \text{ mm} + 7.5 \text{ mm} = 9.5 \text{ mm}
\]

### Answer: 9.5 mm

Problem: A rocket travels 11/18 light-years to an alien planet, then travels another 8/2 light-years towards a distant star. What is the total distance covered by the rocket?

GPT-4o:

First, we need to determine the distance the rocket travels towards the distant star. The given distance is \( \frac{8}{2} \) light-years.

\[
\frac{8}{2} = 4 \text{ light-years}
\]

Next, we add the distances traveled to the alien planet and towards the distant star:

\[
\frac{11}{18} \text{ light-years} + 4 \text{ light-years}
\]

To add these fractions, we need a common denominator. The common denominator for 18 and 1 is 18. We convert 4 light-years to a fraction with a denominator of 18:

\[
4 = \frac{4 \times 18}{1 \times 18} = \frac{72}{18}
\]

Now, we add the fractions:

\[
\frac{11}{18} + \frac{72}{18} = \frac{11 + 72}{18} = \frac{83}{18}
\]

Thus, the total distance covered by the rocket is:

GPT-4o:

To find the total distance covered by the rocket, we need to add the distances traveled to the alien planet and towards the distant star. The distances are \( \frac{11}{18} \) light-years and \( \frac{8}{13} \) light-years, respectively.

First, we need to find a common denominator for the fractions \( \frac{11}{18} \) and \( \frac{8}{13} \). The least common multiple (LCM) of 18 and 13 is 234.

Next, we convert each fraction to have the common denominator of 234:

\[
\frac{11}{18} = \frac{11 \times 13}{18 \times 13} = \frac{143}{234}
\]

\[
\frac{8}{13} = \frac{8 \times 18}{13 \times 18} = \frac{144}{234}
\]

Now, we add the fractions:

\[
\frac{143}{234} + \frac{144}{234} = \frac{143 + 144}{234} = \frac{287}{234}
\]

Thus, the total distance covered by the rocket is:

\[
\frac{287}{234} \text{ light-years}
\]

### Answer: \(\frac{287}{234}\) light-years

To find the total amount of fabric Johnathan needs, we need to add the two fractions: \( \frac{12}{14} \) and \( \frac{8}{5} \).

First, simplify \( \frac{12}{14} \):
\[ \frac{12}{14} = \frac{6}{7} \]

Next, we need a common denominator to add \( \frac{6}{7} \) and \( \frac{8}{5} \). The least common multiple of 7 and 5 is 35.

Convert \( \frac{6}{7} \) to a fraction with a denominator of 35:
\[ \frac{6}{7} = \frac{6 \times 5}{7 \times 5} = \frac{30}{35} \]

Convert \( \frac{8}{5} \) to a fraction with a denominator of 35:
\[ \frac{8}{5} = \frac{8 \times 7}{5 \times 7} = \frac{56}{35} \]

Now, add the two fractions:

Problem: After calculating the total fabrics Jonathan needed for the sleeping bag, he remembered that he had bought 17 yards of fabric in total. How many yards does he have left after using the necessary fabric to create his sleeping bag?

GPT-4o:

To determine how many yards of fabric Johnathan has left after using the necessary fabric, we need to subtract the total fabric used from the total fabric he bought.

Johnathan bought 17 yards of fabric in total. He used \( 2 \frac{16}{35} \) yards for the sleeping bag.

First, convert \( 2 \frac{16}{35} \) to an improper fraction:
\[ 2 \frac{16}{35} = \frac{2 \times 35 + 16}{35} = \frac{70 + 16}{35} = \frac{86}{35} \]

Next, convert 17 yards to a fraction with the same denominator (35):
\[ 17 = \frac{17 \times 35}{35} = \frac{595}{35} \]

Now, subtract the fabric used from the total fabric bought:
\[ \frac{595}{35} - \frac{86}{35} = \frac{595 - 86}{35} = \frac{509}{35} \]

Convert the improper fraction \( \frac{509}{35} \) to a mixed number:
\[ \frac{509}{35} = 14 \frac{19}{35} \]

But after rechecking his measurements, he realized he only needed 12/17 yards of that fabric. The liner fabric remained the same at 8/5 yards. How many total yards of fabric does he actually need to make the sleeping bag?

GPT-4o:

To find the total amount of fabric Johnathan actually needs, we need to add the two fractions: \( \frac{12}{17} \) and \( \frac{8}{5} \).

First, we need a common denominator to add \( \frac{12}{17} \) and \( \frac{8}{5} \). The least common multiple of 17 and 5 is 85.

Convert \( \frac{12}{17} \) to a fraction with a denominator of 85:
\[ \frac{12}{17} = \frac{12 \times 5}{17 \times 5} = \frac{60}{85} \]

Convert \( \frac{8}{5} \) to a fraction with a denominator of 85:
\[ \frac{8}{5} = \frac{8 \times 17}{5 \times 17} = \frac{136}{85} \]

Now, add the two fractions:
\[ \frac{60}{85} + \frac{136}{85} = \frac{60 + 136}{85} = \frac{196}{85} \]

Simplify \( \frac{196}{85} \):
\[ \frac{196}{85} \text{ is already in its simplest form.} \]

First, let's write down the fractions:
- Pine trees: \( \frac{5}{4} \) acres
- Oak trees: \( \frac{1}{2} \) acres

To add these fractions, we need a common denominator. The least common multiple of 4 and 2 is 4. So, we convert \( \frac{1}{2} \) to a fraction with a denominator of 4:

\[ \frac{1}{2} = \frac{1 \times 2}{2 \times 2} = \frac{2}{4} \]

Now we can add the fractions:

\[ \frac{5}{4} + \frac{2}{4} = \frac{5 + 2}{4} = \frac{7}{4} \]

GPT-4o:

To find out how much fabric Jake has in total, we need to add the two fractions together. 

First, let's simplify the fractions if possible:
- The first fraction is \( \frac{12}{7} \), which is already in its simplest form.
- The second fraction is \( \frac{2}{14} \). We can simplify this by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
  \[
  \frac{2}{14} = \frac{2 \div 2}{14 \div 2} = \frac{1}{7}

Now, we need to add \( \frac{12}{7} \) and \( \frac{1}{7} \). Since the denominators are the same, we can simply add the numerators:
\[
\frac{12}{7} + \frac{1}{7} = \frac{12 + 1}{7} = \frac{13}{7}

GPT-4o:

First, we need to determine how much fabric Jake has initially, which is \( \frac{13}{7} \) yards. 

Next, we need to subtract \( \frac{4}{16} \) yards from this amount. Let's simplify \( \frac{4}{16} \) first:
\[
\frac{4}{16} = \frac{4 \div 4}{16 \div 4} = \frac{1}{4}
\]

Now, we need to subtract \( \frac{1}{4} \) from \( \frac{13}{7} \). To do this, we need a common denominator. The least common multiple of 7 and 4 is 28. We convert both fractions to have this common denominator:

\[
\frac{13}{7} = \frac{13 \times 4}{7 \times 4} = \frac{52}{28}
\]
\[
\frac{1}{4} = \frac{1 \times 7}{4 \times 7} = \frac{7}{28}
\]

Now, we subtract the two fractions:
\[
\frac{52}{28} - \frac{7}{28} = \frac{52 - 7}{28} = \frac{45}{28}
\]

So, after making the adjustment, Jake will have \( \frac{45}{28} \) yards of fabric left.

GPT-4o:

First, let's simplify the fractions if possible:

- The first fraction is \( \frac{12}{6} \). We can simplify this by dividing both the numerator and the denominator by their greatest common divisor, which is 6:
  \[
  \frac{12}{6} = \frac{12 \div 6}{6 \div 6} = \frac{2}{1} = 2
  \]

- The second fraction is \( \frac{2}{14} \). We can simplify this by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
  \[
  \frac{2}{14} = \frac{2 \div 2}{14 \div 2} = \frac{1}{7}
  \]

Now, we need to add \( 2 \) and \( \frac{1}{7} \). To do this, we convert 2 to a fraction with the same denominator as \( \frac{1}{7} \):
\[
2 = \frac{2 \times 7}{1 \times 7} = \frac{14}{7}
\]

Now, we can add the two fractions:
\[
\frac{14}{7} + \frac{1}{7} = \frac{14 + 1}{7} = \frac{15}{7}
\]

So, Jake has \( \frac{15}{7} \) yards of fabric in total.

GPT-4o:

To find the new length of the ballerina's routine after shortening it, we need to subtract the time she shortened from the original routine time.

First, let's convert both fractions to have a common denominator so we can subtract them easily. The denominators are 5 and 16. The least common multiple of 5 and 16 is 80.

Convert \( \frac{13}{5} \) to a fraction with a denominator of 80:
\[ \frac{13}{5} = \frac{13 \times 16}{5 \times 16} = \frac{208}{80} \]

Convert \( \frac{15}{16} \) to a fraction with a denominator of 80:
\[ \frac{15}{16} = \frac{15 \times 5}{16 \times 5} = \frac{75}{80} \]

Now, subtract \( \frac{75}{80} \) from \( \frac{208}{80} \):
\[ \frac{208}{80} - \frac{75}{80} = \frac{208 - 75}{80} = \frac{133}{80} \]

So, the new length of the ballerina's routine is \( \frac{133}{80} \) minutes.

To find the new length of the ballerina's routine after adding the new dance move, we need to add \( \frac{2}{20} \) minutes to the current routine length of \( \frac{133}{80} \) minutes.

First, simplify \( \frac{2}{20} \):
\[ \frac{2}{20} = \frac{1}{10} \]

Next, convert \( \frac{1}{10} \) to a fraction with a denominator of 80 to match \( \frac{133}{80} \):
\[ \frac{1}{10} = \frac{1 \times 8}{10 \times 8} = \frac{8}{80} \]

Now, add \( \frac{8}{80} \) to \( \frac{133}{80} \):
\[ \frac{133}{80} + \frac{8}{80} = \frac{133 + 8}{80} = \frac{141}{80} \]

So, the new length of the ballerina's routine is \( \frac{141}{80} \) minutes.

### Answer: \(\frac{141}{80}\) minutes

Problem: If originally the ballerina's routine lasted 13/5 minutes but she had only shortened it by 12/16 minutes instead of 15/16 minutes, how long would her routine be then?

GPT-4o:

To find the new length of the ballerina's routine after shortening it by \( \frac{12}{16} \) minutes, we need to subtract \( \frac{12}{16} \) from the original routine time of \( \frac{13}{5} \).

First, let's convert both fractions to have a common denominator. The denominators are 5 and 16. The least common multiple of 5 and 16 is 80.

Convert \( \frac{13}{5} \) to a fraction with a denominator of 80:
\[ \frac{13}{5} = \frac{13 \times 16}{5 \times 16} = \frac{208}{80} \]

Convert \( \frac{12}{16} \) to a fraction with a denominator of 80:
\[ \frac{12}{16} = \frac{12 \times 5}{16 \times 5} = \frac{60}{80} \]

Now, subtract \( \frac{60}{80} \) from \( \frac{208}{80} \):
\[ \frac{208}{80} - \frac{60}{80} = \frac{208 - 60}{80} = \frac{148}{80} \]

Simplify \( \frac{148}{80} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{148 \div 4}{80 \div 4} = \frac{37}{20} \]

So, the new length of the ballerina's routine is \( \frac{37}{20} \) minutes.

### Answer: \(\frac{37}{20}\) minutes

Expected answer: 37/20

Correct? Yes

Problem: Miss Daisy has 19/6 kg of fertilizers for her flowers. If she uses 17/20 kg on her roses, how much fertilizers does she have left to use on her other flowers?

GPT-4o:

To determine how much fertilizer Miss Daisy has left after using some on her roses, we need to subtract the amount used from the total amount she initially had.

First, let's convert both fractions to have a common denominator so we can subtract them easily. The denominators are 6 and 20. The least common multiple (LCM) of 6 and 20 is 60.

Convert \( \frac{19}{6} \) to a fraction with a denominator of 60:
\[ \frac{19}{6} = \frac{19 \times 10}{6 \times 10} = \frac{190}{60} \]

Convert \( \frac{17}{20} \) to a fraction with a denominator of 60:
\[ \frac{17}{20} = \frac{17 \times 3}{20 \times 3} = \frac{51}{60} \]

Now, subtract \( \frac{51}{60} \) from \( \frac{190}{60} \):
\[ \frac{190}{60} - \frac{51}{60} = \frac{190 - 51}{60} = \frac{139}{60} \]

So, Miss Daisy has \( \frac{139}{60} \) kg of fertilizer left.

### Answer: \( \frac{139}{60} \) kg

Expected answer: 139/60

Correct? Yes

🔗 Follow-up

Problem: Following up on the previous scenario, Miss Daisy finds an additional 11/11 kg of fertilizer in her shed. After she took away 17/20 kg from the original 19/6 kg to use on her roses, she added this new amount to the fertilizer she had left. How much fertilizer does she have now?

GPT-4o:

First, let's recall the amount of fertilizer Miss Daisy had left after using some on her roses. We previously calculated that she had \( \frac{139}{60} \) kg left.

Next, we need to add the additional \( \frac{11}{11} \) kg of fertilizer she found in her shed. Note that \( \frac{11}{11} \) is equivalent to 1 kg.

To add these two amounts, we need a common denominator. The denominator of \( \frac{139}{60} \) is 60, and the denominator of 1 kg (which can be written as \( \frac{60}{60} \)) is also 60.

Now, add the two fractions:
\[ \frac{139}{60} + \frac{60}{60} = \frac{139 + 60}{60} = \frac{199}{60} \]

So, Miss Daisy now has \( \frac{199}{60} \) kg of fertilizer.

Problem: Continuing from the scenario, suppose instead of the initial 19/6 kg of fertilizers, Miss Daisy had only 14/6 kg of fertilizers. If she still uses 17/20 kg on her roses, how much fertilizers does she have left to use on her other flowers now?

GPT-4o:

To determine how much fertilizer Miss Daisy has left after using some on her roses, we need to subtract the amount used from the new total amount she initially had.

First, let's convert both fractions to have a common denominator so we can subtract them easily. The denominators are 6 and 20. The least common multiple (LCM) of 6 and 20 is 60.

Convert \( \frac{14}{6} \) to a fraction with a denominator of 60:
\[ \frac{14}{6} = \frac{14 \times 10}{6 \times 10} = \frac{140}{60} \]

Convert \( \frac{17}{20} \) to a fraction with a denominator of 60:
\[ \frac{17}{20} = \frac{17 \times 3}{20 \times 3} = \frac{51}{60} \]

Now, subtract \( \frac{51}{60} \) from \( \frac{140}{60} \):
\[ \frac{140}{60} - \frac{51}{60} = \frac{140 - 51}{60} = \frac{89}{60} \]

So, Miss Daisy has \( \frac{89}{60} \) kg of fertilizer left.

### Answer: \( \frac{89}{60} \) kg

Problem: Scientists have discovered that the moon is slowly moving away from Earth. If the distance increases by 4/16 meters every year, and unexpectedly there was an additional increase of 20/6 meters this year, what is the total change in distance this year?

GPT-4o:

First, let's simplify the fractions given in the problem.

The annual increase in distance is:
\[ \frac{4}{16} \]
Simplifying \(\frac{4}{16}\):
\[ \frac{4}{16} = \frac{1}{4} \]

The additional increase this year is:
\[ \frac{20}{6} \]
Simplifying \(\frac{20}{6}\):
\[ \frac{20}{6} = \frac{10}{3} \]

Now, we need to find the total change in distance this year by adding these two fractions:
\[ \frac{1}{4} + \frac{10}{3} \]

To add these fractions, we need a common denominator. The least common multiple of 4 and 3 is 12. We convert each fraction to have this common denominator:
\[ \frac{1}{4} = \frac{1 \times 3}{4 \times 3} = \frac{3}{12} \]
\[ \frac{10}{3} = \frac{10 \times 4}{3 \times 4} = \frac{40}{12} \]

Now, we add the fractions:
\[ \frac{3}{12} + \frac{40}{12} = \frac{3 + 40}{12} = \frac{43}{12} \]

Thus, the total change in distance this year is:
\[ \frac{43}{12} \]

### Answer: \(\frac{43}{12}\) meters

Correct? Yes

🔗 Follow-up

Problem: Building upon the previous scenario, if scientists predict an additional increase of 16/6 meters in the coming year, what will be the total expected change in distance from Earth to the moon after this increase?

GPT-4o:

To find the total expected change in distance from Earth to the moon after the additional increase, we need to add the previous total change in distance to the new predicted increase.

From the previous calculation, the total change in distance this year was:
\[ \frac{43}{12} \]

The additional predicted increase for the coming year is:
\[ \frac{16}{6} \]
Simplifying \(\frac{16}{6}\):
\[ \frac{16}{6} = \frac{8}{3} \]

Next, we need to add these two fractions. To do this, we need a common denominator. The least common multiple of 12 and 3 is 12. We convert \(\frac{8}{3}\) to have this common denominator:
\[ \frac{8}{3} = \frac{8 \times 4}{3 \times 4} = \frac{32}{12} \]

Now, we add the fractions:
\[ \frac{43}{12} + \frac{32}{12} = \frac{43 + 32}{12} = \frac{75}{12} \]

Thus, the total expected change in distance from Earth to the moon after the additional increase is:
\[ \frac{75}{12} \]

### Answer: \(\frac{75}{12}\) meters

Problem: Continuing from the previous scenario, suppose scientists later realized that there was a calculation error. Instead of an unexpected increase of 20/6 meters in the moon's distance this year, they found the increase was actually 20/18 meters. Given this corrected value, what is the total change in distance from the Earth to the moon this year?

GPT-4o:

First, let's simplify the fractions given in the problem.

The annual increase in distance is:
\[ \frac{4}{16} \]
Simplifying \(\frac{4}{16}\):
\[ \frac{4}{16} = \frac{1}{4} \]

The corrected additional increase this year is:
\[ \frac{20}{18} \]
Simplifying \(\frac{20}{18}\):
\[ \frac{20}{18} = \frac{10}{9} \]

Now, we need to find the total change in distance this year by adding these two fractions:
\[ \frac{1}{4} + \frac{10}{9} \]

To add these fractions, we need a common denominator. The least common multiple of 4 and 9 is 36. We convert each fraction to have this common denominator:
\[ \frac{1}{4} = \frac{1 \times 9}{4 \times 9} = \frac{9}{36} \]
\[ \frac{10}{9} = \frac{10 \times 4}{9 \times 4} = \frac{40}{36} \]

Now, we add the fractions:
\[ \frac{9}{36} + \frac{40}{36} = \frac{9 + 40}{36} = \frac{49}{36} \]

Thus, the total change in distance this year is:
\[ \frac{49}{36} \]

### Answer: \(\frac{49}{36}\) meters

Problem: Bob has 11/3 dollars in one pocket of his wallet and 12/19 dollars in another pocket. How much money does he have in total in his wallet?

GPT-4o:

To find the total amount of money Bob has in his wallet, we need to add the two fractions together: \(\frac{11}{3}\) and \(\frac{12}{19}\).

First, we need a common denominator for the fractions. The least common multiple (LCM) of 3 and 19 is 57.

Next, we convert each fraction to have the common denominator of 57:
\[
\frac{11}{3} = \frac{11 \times 19}{3 \times 19} = \frac{209}{57}
\]
\[
\frac{12}{19} = \frac{12 \times 3}{19 \times 3} = \frac{36}{57}
\]

Now, we add the two fractions:
\[
\frac{209}{57} + \frac{36}{57} = \frac{209 + 36}{57} = \frac{245}{57}
\]

To simplify \(\frac{245}{57}\), we check if there is a common factor between 245 and 57. Since there is no common factor other than 1, the fraction is already in its simplest form.

Thus, the total amount of money Bob has in his wallet is \(\frac{245}{57}\) dollars.

Problem: Bob has 11/3 dollars in one pocket of his wallet and 12/19 dollars in another pocket. How much money does he have in total in his wallet? Now, if Bob duplicates the total amount of money in his wallet, how much money will he have then?

GPT-4o:

First, we need to find the total amount of money Bob has in his wallet by adding the two fractions: \(\frac{11}{3}\) and \(\frac{12}{19}\).

To add these fractions, we need a common denominator. The least common multiple (LCM) of 3 and 19 is 57.

Convert each fraction to have the common denominator of 57:
\[
\frac{11}{3} = \frac{11 \times 19}{3 \times 19} = \frac{209}{57}
\]
\[
\frac{12}{19} = \frac{12 \times 3}{19 \times 3} = \frac{36}{57}
\]

Now, add the two fractions:
\[
\frac{209}{57} + \frac{36}{57} = \frac{209 + 36}{57} = \frac{245}{57}
\]

Next, if Bob duplicates the total amount of money in his wallet, we need to multiply the total by 2:
\[
2 \times \frac{245}{57} = \frac{2 \times 245}{57} = \frac{490}{57}
\]

To simplify \(\frac{490}{57}\), we check if there is a common factor between 490 and 57. Since there is no common factor other than 1, the fraction is already in its simplest form.

Thus, the total amount of money Bob will have after duplicating is \(\frac{490}{57}\) dollars.

Problem: Suppose Bob starts out with 3/3 (or 1) dollar in one pocket of his wallet instead of 11/3 dollars, and still has 12/19 dollars in another pocket. Now how much money does he have in total in his wallet?

GPT-4o:

To find the total amount of money Bob has in his wallet, we need to add the two fractions together: \(\frac{3}{3}\) and \(\frac{12}{19}\).

First, we recognize that \(\frac{3}{3}\) is equivalent to 1. So, we need to add 1 dollar to \(\frac{12}{19}\) dollars.

To add these, we convert 1 to a fraction with the same denominator as \(\frac{12}{19}\):
\[
1 = \frac{19}{19}
\]

Now, we add the two fractions:
\[
\frac{19}{19} + \frac{12}{19} = \frac{19 + 12}{19} = \frac{31}{19}
\]

Thus, the total amount of money Bob has in his wallet is \(\frac{31}{19}\) dollars.

Problem: In an ocean, a shark swims a distance of 5/5 miles in the morning and adds an additional 12/18 miles in the afternoon. How many miles in total did the shark swim that day?

GPT-4o:

First, we need to simplify the fractions to make the calculations easier.

The distance the shark swims in the morning is:
\[ \frac{5}{5} = 1 \text{ mile} \]

Next, we simplify the fraction for the distance swum in the afternoon:
\[ \frac{12}{18} \]
We can simplify this by finding the greatest common divisor (GCD) of 12 and 18, which is 6:
\[ \frac{12 \div 6}{18 \div 6} = \frac{2}{3} \text{ miles} \]

Now, we add the distances swum in the morning and the afternoon:
\[ 1 + \frac{2}{3} \]

To add these, we convert 1 to a fraction with the same denominator as \(\frac{2}{3}\):
\[ 1 = \frac{3}{3} \]

Now, we add the fractions:
\[ \frac{3}{3} + \frac{2}{3} = \frac{3 + 2}{3} = \frac{5}{3} \]

Finally, we convert \(\frac{5}{3}\) to a mixed number:

Problem: Following the previous problem, if the shark decides to swim an additional 18/9 miles in the evening, what is the total distance the shark would have swam by the end of the day?

GPT-4o:

First, we need to simplify the fraction for the distance swum in the evening:
\[ \frac{18}{9} \]
We can simplify this by dividing both the numerator and the denominator by their greatest common divisor, which is 9:
\[ \frac{18 \div 9}{9 \div 9} = \frac{2}{1} = 2 \text{ miles} \]

From the previous problem, we know the shark swam a total of \(1 \frac{2}{3}\) miles in the morning and afternoon. We can convert this mixed number to an improper fraction for easier addition:
\[ 1 \frac{2}{3} = \frac{3}{3} + \frac{2}{3} = \frac{5}{3} \]

Now, we add the distance swum in the evening:
\[ \frac{5}{3} + 2 \]

To add these, we convert 2 to a fraction with the same denominator as \(\frac{5}{3}\):
\[ 2 = \frac{6}{3} \]

Now, we add the fractions:
\[ \frac{5}{3} + \frac{6}{3} = \frac{5 + 6}{3} = \frac{11}{3} \]

GPT-4o:

First, we need to determine the typing speed of Jim and Mary in words per second.

For Jim:
Jim types 20 words in 16 seconds.
To find his typing speed in words per second, we divide the number of words by the number of seconds:
\[ \text{Jim's typing speed} = \frac{20 \text{ words}}{16 \text{ seconds}} = 1.25 \text{ words per second} \]

For Mary:
Mary types 9 words in 4 seconds.
To find her typing speed in words per second, we divide the number of words by the number of seconds:

Problem: At a circus, a clown rode a unicycle for 9/8 hours. After a short break, she juggled for another 2/10 hours. How many hours in total did she perform?

GPT-4o:

To find the total time the clown performed, we need to add the time she spent riding the unicycle and the time she spent juggling.

First, let's convert the fractions to have a common denominator. The denominators are 8 and 10. The least common multiple of 8 and 10 is 40.

Convert \( \frac{9}{8} \) to a fraction with a denominator of 40:
\[ \frac{9}{8} = \frac{9 \times 5}{8 \times 5} = \frac{45}{40} \]

Convert \( \frac{2}{10} \) to a fraction with a denominator of 40:
\[ \frac{2}{10} = \frac{2 \times 4}{10 \times 4} = \frac{8}{40} \]

Now, add the two fractions:
\[ \frac{45}{40} + \frac{8}{40} = \frac{45 + 8}{40} = \frac{53}{40} \]

Convert the improper fraction \( \frac{53}{40} \) to a mixed number:
\[ \frac{53}{40} = 1 \frac{13}{40} \]

GPT-4o:

To find out how many hours remained after the clown's performance time is subtracted from her total break time, we need to subtract the performance time from the break time.

The performance time is \( 1 \frac{13}{40} \) hours, which can be converted to an improper fraction:
\[ 1 \frac{13}{40} = \frac{40}{40} + \frac{13}{40} = \frac{53}{40} \]

The break time is \( \frac{13}{5} \) hours. To subtract these two fractions, we need a common denominator. The denominators are 40 and 5. The least common multiple of 40 and 5 is 40.

Convert \( \frac{13}{5} \) to a fraction with a denominator of 40:
\[ \frac{13}{5} = \frac{13 \times 8}{5 \times 8} = \frac{104}{40} \]

Now, subtract the performance time from the break time:
\[ \frac{104}{40} - \frac{53}{40} = \frac{104 - 53}{40} = \frac{51}{40} \]

Convert the improper fraction \( \frac{51}{40} \) to a mixed number:

Convert \( \frac{9}{8} \) to a fraction with a denominator of 40:
\[ \frac{9}{8} = \frac{9 \times 5}{8 \times 5} = \frac{45}{40} \]

Convert \( \frac{9}{10} \) to a fraction with a denominator of 40:
\[ \frac{9}{10} = \frac{9 \times 4}{10 \times 4} = \frac{36}{40} \]

Now, add the two fractions:
\[ \frac{45}{40} + \frac{36}{40} = \frac{45 + 36}{40} = \frac{81}{40} \]

Convert the improper fraction \( \frac{81}{40} \) to a mixed number:
\[ \frac{81}{40} = 2 \frac{1}{40} \]

So, the total time the clown performed is \( 2 \frac{1}{40} \) hours.

### Answer: 2 \(\frac{1}{40}\) hours

Problem: If Timmy dumps 7/2 kg of sand into his sandbox and later adds another 1/2 kg, how much sand is now in his sandbox?

GPT-4o:

To determine the total amount of sand in Timmy's sandbox, we need to add the two quantities of sand together.

First, we have:
\[ \frac{7}{2} \text{ kg} \]

Next, Timmy adds:
\[ \frac{1}{2} \text{ kg} \]

To add these fractions, we need a common denominator. Since both fractions already have the same denominator (2), we can simply add the numerators:

\[ \frac{7}{2} + \frac{1}{2} = \frac{7 + 1}{2} = \frac{8}{2} \]

Now, simplify the fraction:

\[ \frac{8}{2} = 4 \text{ kg} \]

### Answer: 4 kg

Expected answer: 4

Correct? Yes

🔗 Follow-up

Problem: Following the last scenario, if Timmy later dumps another 16/3 kg of sand into the sandbox, how much sand does the sandbox contain now?

GPT-4o:

To find the total amount of sand in the sandbox after Timmy adds another \( \frac{16}{3} \) kg, we need to add this new amount to the existing 4 kg of sand.

First, we convert 4 kg to a fraction with a common denominator of 3:

\[ 4 \text{ kg} = \frac{4 \times 3}{1 \times 3} = \frac{12}{3} \]

Now, we add the two fractions:

\[ \frac{12}{3} + \frac{16}{3} = \frac{12 + 16}{3} = \frac{28}{3} \]

So, the total amount of sand in the sandbox is:

\[ \frac{28}{3} \text{ kg} \]

### Answer: \(\frac{28}{3}\) kg

Expected answer: 28/3

Problem: In the previous sandbox problem, if Timmy initially dumped 7/2 kg of sand into his sandbox but this time around, he decided to add only 1/20 kg of sand to it instead, how much sand is now in his sandbox?

GPT-4o:

To determine the total amount of sand in Timmy's sandbox, we need to add the two quantities of sand together.

First, we have:
\[ \frac{7}{2} \text{ kg} \]

Next, Timmy adds:
\[ \frac{1}{20} \text{ kg} \]

To add these fractions, we need a common denominator. The least common multiple of 2 and 20 is 20. We convert \(\frac{7}{2}\) to a fraction with a denominator of 20:

\[ \frac{7}{2} = \frac{7 \times 10}{2 \times 10} = \frac{70}{20} \]

Now, we can add the two fractions:

\[ \frac{70}{20} + \frac{1}{20} = \frac{70 + 1}{20} = \frac{71}{20} \]

This fraction can be left as is or converted to a mixed number:

\[ \frac{71}{20} = 3 \frac{11}{20} \]

### Answer: \(\frac{71}{20}\) or \(3 \frac{11}{20}\) kg

Problem: A wizard brewed a potion that required 18/8 ounces of moon roots and 11/7 ounces of stardust. How many ounces of ingredients did the wizard use in total to prepare the potion?

GPT-4o:

To find the total amount of ingredients used, we need to add the two fractions: \( \frac{18}{8} \) and \( \frac{11}{7} \).

First, we need a common denominator for the fractions. The denominators are 8 and 7. The least common multiple (LCM) of 8 and 7 is 56.

Next, we convert each fraction to have the common denominator of 56:

\[
\frac{18}{8} = \frac{18 \times 7}{8 \times 7} = \frac{126}{56}
\]

\[
\frac{11}{7} = \frac{11 \times 8}{7 \times 8} = \frac{88}{56}
\]

Now, we add the two fractions:

\[
\frac{126}{56} + \frac{88}{56} = \frac{126 + 88}{56} = \frac{214}{56}
\]

To simplify \( \frac{214}{56} \), we find the greatest common divisor (GCD) of 214 and 56, which is 2:

\[
\frac{214 \div 2}{56 \div 2} = \frac{107}{28}
\]

Thus, the wizard used \( \frac{107}{28} \) ounces of ingredients in total.

### Answer: \(\frac{107}{28}\) ounces

GPT-4o:

To find the total amount of ingredients used with the adjusted amount of stardust, we need to add the fractions \( \frac{18}{8} \) and \( \frac{13}{7} \).

First, we need a common denominator for the fractions. The denominators are 8 and 7. The least common multiple (LCM) of 8 and 7 is 56.

Next, we convert each fraction to have the common denominator of 56:

\[
\frac{18}{8} = \frac{18 \times 7}{8 \times 7} = \frac{126}{56}
\]

\[
\frac{13}{7} = \frac{13 \times 8}{7 \times 8} = \frac{104}{56}
\]

Now, we add the two fractions:

\[
\frac{126}{56} + \frac{104}{56} = \frac{126 + 104}{56} = \frac{230}{56}
\]

To simplify \( \frac{230}{56} \), we find the greatest common divisor (GCD) of 230 and 56, which is 2:

\[
\frac{230 \div 2}{56 \div 2} = \frac{115}{28}
\]

Thus, the wizard used \( \frac{115}{28} \) ounces of ingredients in total with the adjusted recipe.

### Answer: \(\frac{115}{28}\) ounces

Problem: An alien UFO traveled 3/10 of a mile, then immediately traveled an additional 16/20 of a mile. How many miles did the UFO travel in total?

GPT-4o:

To find the total distance the UFO traveled, we need to add the two distances together. First, let's convert both fractions to have a common denominator.

The fractions are:
\[ \frac{3}{10} \]
\[ \frac{16}{20} \]

We can simplify \(\frac{16}{20}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{16 \div 4}{20 \div 4} = \frac{4}{5} \]

Next, we need a common denominator for \(\frac{3}{10}\) and \(\frac{4}{5}\). The least common multiple of 10 and 5 is 10. We can convert \(\frac{4}{5}\) to a fraction with a denominator of 10:
\[ \frac{4}{5} = \frac{4 \times 2}{5 \times 2} = \frac{8}{10} \]

Now we can add the two fractions:
\[ \frac{3}{10} + \frac{8}{10} = \frac{3 + 8}{10} = \frac{11}{10} \]

The total distance the UFO traveled is \(\frac{11}{10}\) miles, which can also be expressed as 1.1 miles.

### Answer: 1.1 miles

Problem: A chair manufacturing firm makes 4/14 of a chair every hour with one machine, and another machine makes 20/4 chairs. How many chairs are made by both machines in one hour?

GPT-4o:

First, let's determine how many chairs the first machine makes in one hour. The first machine makes \( \frac{4}{14} \) of a chair every hour. We can simplify this fraction:

\[
\frac{4}{14} = \frac{2}{7}
\]

So, the first machine makes \( \frac{2}{7} \) of a chair every hour.

Next, let's determine how many chairs the second machine makes in one hour. The second machine makes \( \frac{20}{4} \) chairs every hour. Simplifying this fraction:

\[
\frac{20}{4} = 5
\]

So, the second machine makes 5 chairs every hour.

To find the total number of chairs made by both machines in one hour, we add the number of chairs made by each machine:

\[
\frac{2}{7} + 5
\]

To add these, we need a common denominator. The common denominator for 7 and 1 is 7. Converting 5 to a fraction with a denominator of 7:

\[
5 = \frac{35}{7}
\]

Now, we can add the fractions:

\[
\frac{2}{7} + \frac{35}{7} = \frac{2 + 35}{7} = \frac{37}{7}
\]

So, the total number of chairs made by both machines in one hour is \( \frac{37}{7} \).

### Answer: \(\frac{37}{7}\)

Problem: In the chair manufacturing firm discussed before, let's say the first machine was originally making 17/14 of a chair every hour instead of 4/14. How many chairs are now made by both machines in one hour?

GPT-4o:

First, let's determine how many chairs the first machine makes in one hour with the new rate. The first machine now makes \( \frac{17}{14} \) of a chair every hour.

Next, we already know that the second machine makes \( 5 \) chairs every hour.

To find the total number of chairs made by both machines in one hour, we add the number of chairs made by each machine:

\[
\frac{17}{14} + 5
\]

To add these, we need a common denominator. The common denominator for 14 and 1 is 14. Converting 5 to a fraction with a denominator of 14:

\[
5 = \frac{70}{14}
\]

Now, we can add the fractions:

\[
\frac{17}{14} + \frac{70}{14} = \frac{17 + 70}{14} = \frac{87}{14}
\]

So, the total number of chairs made by both machines in one hour is \( \frac{87}{14} \).

Problem: After the blue shark and the hammerhead shark swam their respective distances, a great white shark joined them and swam 9/14 miles. What is the total combined distance that the three sharks swam together?

GPT-4o:

To find the total combined distance swum by the three sharks, we need to add the distances swum by the blue shark, the hammerhead shark, and the great white shark.

From the previous problem, we know that the blue shark and the hammerhead shark swam a combined distance of \( \frac{6}{5} \) miles.

Now, we need to add the distance swum by the great white shark, which is \( \frac{9}{14} \) miles.

First, we need to find a common denominator for the fractions \( \frac{6}{5} \) and \( \frac{9}{14} \). The least common multiple (LCM) of 5 and 14 is 70.

Convert \( \frac{6}{5} \) to a fraction with a denominator of 70:
\[ \frac{6}{5} = \frac{6 \times 14}{5 \times 14} = \frac{84}{70} \]

Convert \( \frac{9}{14} \) to a fraction with a denominator of 70:
\[ \frac{9}{14} = \frac{9 \times 5}{14 \times 5} = \frac{45}{70} \]

Now, add the two fractions:
\[ \frac{84}{70} + \frac{45}{70} = \frac{84 + 45}{70} = \frac{129}{70} \]

Problem: A tree grows 1/10 of its height every month. This month, it additionally has grown 12/6 feet due to a fertilizer being applied. How much has the tree grown in height this month?

GPT-4o:

First, let's simplify the additional growth due to the fertilizer. The expression \( \frac{12}{6} \) simplifies to:

\[
\frac{12}{6} = 2 \text{ feet}
\]

Next, we need to consider the growth of the tree due to its natural growth rate, which is \( \frac{1}{10} \) of its height every month. However, since the problem does not specify the initial height of the tree, we will focus on the given additional growth.

Therefore, the total growth of the tree this month is the sum of its natural growth and the additional growth due to the fertilizer. Since the natural growth rate is not specified in terms of the tree's height, we only consider the additional growth:

\[
2 \text{ feet}
\]

To find the total area occupied by both tents, we need to add the areas of the two tents together.

First, let's convert the fractions to have a common denominator. The denominators are 11 and 20. The least common multiple (LCM) of 11 and 20 is 220.

Convert \( \frac{13}{11} \) to a fraction with a denominator of 220:
\[ \frac{13}{11} = \frac{13 \times 20}{11 \times 20} = \frac{260}{220} \]

Convert \( \frac{8}{20} \) to a fraction with a denominator of 220:
\[ \frac{8}{20} = \frac{8 \times 11}{20 \times 11} = \frac{88}{220} \]

Now, add the two fractions:
\[ \frac{260}{220} + \frac{88}{220} = \frac{260 + 88}{220} = \frac{348}{220} \]

Simplify the fraction by finding the greatest common divisor (GCD) of 348 and 220. The GCD of 348 and 220 is 4.

Divide both the numerator and the denominator by their GCD:

Problem: Captain Jack has a treasure map that shows the treasure is at a location that is (17 / 20) km to the East and then (15 / 3) km to the North from their starting point. How far must they travel in total to reach the treasure?

GPT-4o:

First, let's determine the distances Captain Jack needs to travel in each direction.

To the East:
\[ \frac{17}{20} \text{ km} \]

To the North:
\[ \frac{15}{3} \text{ km} = 5 \text{ km} \]

Now, we add these distances to find the total distance traveled:
\[ \frac{17}{20} \text{ km} + 5 \text{ km} \]

To add these, we need a common denominator. The common denominator for 20 and 1 is 20. So, we convert 5 km to a fraction with a denominator of 20:
\[ 5 \text{ km} = \frac{5 \times 20}{1 \times 20} = \frac{100}{20} \text{ km} \]

Now, we can add the fractions:
\[ \frac{17}{20} \text{ km} + \frac{100}{20} \text{ km} = \frac{17 + 100}{20} \text{ km} = \frac{117}{20} \text{ km} \]

To find the total amount of firewood collected by Sarah and Alex, we need to add the amounts they each collected.

Sarah collected \( \frac{11}{20} \) pounds of firewood.
Alex collected \( \frac{9}{7} \) pounds of firewood.

First, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 20 and 7 is 140.

Convert \( \frac{11}{20} \) to a fraction with a denominator of 140:
\[ \frac{11}{20} = \frac{11 \times 7}{20 \times 7} = \frac{77}{140} \]

Convert \( \frac{9}{7} \) to a fraction with a denominator of 140:
\[ \frac{9}{7} = \frac{9 \times 20}{7 \times 20} = \frac{180}{140} \]

Now, add the two fractions:
\[ \frac{77}{140} + \frac{180}{140} = \frac{77 + 180}{140} = \frac{257}{140} \]

Simplify the fraction if possible. In this case, \( \frac{257}{140} \) is already in its simplest form.

Problem: Instead of initially collecting 11/20 of a pound of firewood, let's say Sarah collected only half as much, so 10/20 of a pound of firewood, while Alex still collected 9/7 pounds. How many pounds of firewood did they collect in total now?

GPT-4o:

To find the total amount of firewood collected by Sarah and Alex with the new amounts, we need to add the amounts they each collected.

Sarah collected \( \frac{10}{20} \) pounds of firewood, which simplifies to \( \frac{1}{2} \) pounds.
Alex collected \( \frac{9}{7} \) pounds of firewood.

First, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 2 and 7 is 14.

Convert \( \frac{1}{2} \) to a fraction with a denominator of 14:
\[ \frac{1}{2} = \frac{1 \times 7}{2 \times 7} = \frac{7}{14} \]

Convert \( \frac{9}{7} \) to a fraction with a denominator of 14:
\[ \frac{9}{7} = \frac{9 \times 2}{7 \times 2} = \frac{18}{14} \]

Now, add the two fractions:
\[ \frac{7}{14} + \frac{18}{14} = \frac{7 + 18}{14} = \frac{25}{14} \]

Simplify the fraction if possible. In this case, \( \frac{25}{14} \) is already in its simplest form.

Therefore, the total amount of firewood collected by Sarah and Alex is \( \frac{25}{14} \) pounds.

### Answer: \(\frac{25}{14}\) pounds

Problem: Captain Bill sailed 19/5 miles north, before changing track and sailing an additional 12/15 miles north. How many miles north did Captain Bill sail in total?

GPT-4o:

To find the total distance Captain Bill sailed north, we need to add the two distances together. First, let's convert both fractions to have a common denominator.

The fractions are:
\[ \frac{19}{5} \]
\[ \frac{12}{15} \]

The least common multiple (LCM) of 5 and 15 is 15. We need to convert \(\frac{19}{5}\) to a fraction with a denominator of 15.

\[ \frac{19}{5} = \frac{19 \times 3}{5 \times 3} = \frac{57}{15} \]

Now we can add the two fractions:
\[ \frac{57}{15} + \frac{12}{15} = \frac{57 + 12}{15} = \frac{69}{15} \]

Next, we simplify \(\frac{69}{15}\). Both the numerator and the denominator can be divided by their greatest common divisor, which is 3.

\[ \frac{69 \div 3}{15 \div 3} = \frac{23}{5} \]

So, Captain Bill sailed a total of \(\frac{23}{5}\) miles north.

### Answer: \(\frac{23}{5}\) miles

Problem: After traveling north for a total distance, Captain Bill decided to backtrack and went 20/17 miles south. How many miles away from the original starting point was Captain Bill located then?

GPT-4o:

To determine how far Captain Bill was from his original starting point after backtracking, we need to subtract the distance he traveled south from the total distance he traveled north.

From the previous calculation, we know Captain Bill traveled \(\frac{23}{5}\) miles north. He then traveled \(\frac{20}{17}\) miles south.

First, we need to find a common denominator to subtract these fractions. The least common multiple (LCM) of 5 and 17 is 85.

Convert both fractions to have a denominator of 85:
\[ \frac{23}{5} = \frac{23 \times 17}{5 \times 17} = \frac{391}{85} \]
\[ \frac{20}{17} = \frac{20 \times 5}{17 \times 5} = \frac{100}{85} \]

Now, subtract the two fractions:
\[ \frac{391}{85} - \frac{100}{85} = \frac{391 - 100}{85} = \frac{291}{85} \]

Next, we simplify \(\frac{291}{85}\). Both the numerator and the denominator can be divided by their greatest common divisor, which is 1 (since 291 and 85 have no common factors other than 1).

So, Captain Bill is \(\frac{291}{85}\) miles away from his original starting point.

### Answer: \(\frac{291}{85}\) miles

Expected answer: 291/85

Correct? Yes

Problem: After reconsidering the calculations, Captain Bill realized that he actually sailed 19/18 miles north initially instead of 19/5 miles before changing track and sailing an additional 12/15 miles north. In light of this new information, how many miles north did Captain Bill sail in total now?

GPT-4o:

To find the total distance Captain Bill sailed north with the updated information, we need to add the two distances together. The fractions are:

\[ \frac{19}{18} \]
\[ \frac{12}{15} \]

First, we need to convert both fractions to have a common denominator. The least common multiple (LCM) of 18 and 15 is 90. We will convert each fraction to have a denominator of 90.

For \(\frac{19}{18}\):
\[ \frac{19}{18} = \frac{19 \times 5}{18 \times 5} = \frac{95}{90} \]

For \(\frac{12}{15}\):
\[ \frac{12}{15} = \frac{12 \times 6}{15 \times 6} = \frac{72}{90} \]

Now we can add the two fractions:
\[ \frac{95}{90} + \frac{72}{90} = \frac{95 + 72}{90} = \frac{167}{90} \]

So, Captain Bill sailed a total of \(\frac{167}{90}\) miles north.

### Answer: \(\frac{167}{90}\) miles

Problem: A restaurant uses 19/17 pounds of ham and 9/4 pounds of turkey for their signature sandwich. What is the total weight of the two types of meat per sandwich?

GPT-4o:

To find the total weight of the two types of meat per sandwich, we need to add the fractions representing the weight of the ham and the turkey.

The weights given are:
- Ham: \( \frac{19}{17} \) pounds
- Turkey: \( \frac{9}{4} \) pounds

First, we need a common denominator to add these fractions. The least common multiple (LCM) of 17 and 4 is 68.

Convert each fraction to have a denominator of 68:
\[ \frac{19}{17} = \frac{19 \times 4}{17 \times 4} = \frac{76}{68} \]
\[ \frac{9}{4} = \frac{9 \times 17}{4 \times 17} = \frac{153}{68} \]

Now, add the two fractions:
\[ \frac{76}{68} + \frac{153}{68} = \frac{76 + 153}{68} = \frac{229}{68} \]

Thus, the total weight of the two types of meat per sandwich is:

Problem: After making their signature sandwich, the restaurant staff find that they have used 13/9 pounds more meat than they intended to. What is the weight of the meat that should have been in the sandwich?

GPT-4o:

To find the intended weight of the meat in the sandwich, we need to subtract the excess amount of meat used from the total weight of the meat actually used.

From the previous problem, we know the total weight of the meat used is:
\[ \frac{229}{68} \text{ pounds} \]

The excess amount of meat used is:
\[ \frac{13}{9} \text{ pounds} \]

First, we need a common denominator to subtract these fractions. The least common multiple (LCM) of 68 and 9 is 612.

Convert each fraction to have a denominator of 612:
\[ \frac{229}{68} = \frac{229 \times 9}{68 \times 9} = \frac{2061}{612} \]
\[ \frac{13}{9} = \frac{13 \times 68}{9 \times 68} = \frac{884}{612} \]

Now, subtract the excess amount from the total weight:
\[ \frac{2061}{612} - \frac{884}{612} = \frac{2061 - 884}{612} = \frac{1177}{612} \]

Thus, the weight of the meat that should have been in the sandwich is:
\[ \frac{1177}{612} \]

GPT-4o:

To find the corrected total weight of the ham and turkey meat in the sandwich, we need to add the fractions representing the weight of the ham and the corrected weight of the turkey.

The weights given are:
- Ham: \( \frac{19}{17} \) pounds
- Corrected Turkey: \( \frac{6}{4} \) pounds

First, we need a common denominator to add these fractions. The least common multiple (LCM) of 17 and 4 is 68.

Convert each fraction to have a denominator of 68:
\[ \frac{19}{17} = \frac{19 \times 4}{17 \times 4} = \frac{76}{68} \]
\[ \frac{6}{4} = \frac{6 \times 17}{4 \times 17} = \frac{102}{68} \]

Now, add the two fractions:
\[ \frac{76}{68} + \frac{102}{68} = \frac{76 + 102}{68} = \frac{178}{68} \]

Thus, the corrected total weight of the ham and turkey meat per sandwich is:

Problem: Lucy has a sleeping bag that is 18/19 meter long. She got an extension for her sleeping bag which made it 8/11 meter longer. What's the total length of the sleeping bag now?

GPT-4o:

To find the total length of Lucy's sleeping bag after adding the extension, we need to add the original length of the sleeping bag to the length of the extension.

The original length of the sleeping bag is \( \frac{18}{19} \) meters.
The length of the extension is \( \frac{8}{11} \) meters.

To add these two fractions, we need a common denominator. The least common multiple (LCM) of 19 and 11 is 209.

First, we convert each fraction to have the common denominator of 209:

\[
\frac{18}{19} = \frac{18 \times 11}{19 \times 11} = \frac{198}{209}
\]

\[
\frac{8}{11} = \frac{8 \times 19}{11 \times 19} = \frac{152}{209}
\]

Now, we add the two fractions:

\[
\frac{198}{209} + \frac{152}{209} = \frac{198 + 152}{209} = \frac{350}{209}
\]

Thus, the total length of the sleeping bag is \( \frac{350}{209} \) meters.

### Answer: \(\frac{350}{209}\) meters

Problem: Considering the previous problem, what if Lucy's initial sleeping bag was 18/19 meter long and her extension was only 8/8 meter long. What would be the total length of her sleeping bag then?

GPT-4o:

To find the total length of Lucy's sleeping bag after adding the extension, we need to add the original length of the sleeping bag to the length of the extension.

The original length of the sleeping bag is \( \frac{18}{19} \) meters.
The length of the extension is \( \frac{8}{8} \) meters, which simplifies to 1 meter.

Now, we add these two lengths:

\[
\frac{18}{19} + 1
\]

To add these, we convert 1 to a fraction with the same denominator as \( \frac{18}{19} \):

\[
1 = \frac{19}{19}
\]

Now, we add the two fractions:

\[
\frac{18}{19} + \frac{19}{19} = \frac{18 + 19}{19} = \frac{37}{19}
\]

Thus, the total length of the sleeping bag is \( \frac{37}{19} \) meters.

Problem: Mandy has 9/2 KGs of apples. She uses 1/4 KG of them to make apple pie. How many KGs of apples does she have left?

GPT-4o:

First, we need to determine how many kilograms of apples Mandy uses to make the apple pie. She uses \( \frac{1}{4} \) kg.

Next, we subtract the amount used from the total amount Mandy initially had. Mandy initially had \( \frac{9}{2} \) kg of apples.

To perform the subtraction, we need a common denominator. The common denominator for 2 and 4 is 4. We convert \( \frac{9}{2} \) to a fraction with a denominator of 4:

\[ \frac{9}{2} = \frac{9 \times 2}{2 \times 2} = \frac{18}{4} \]

Now, we subtract \( \frac{1}{4} \) from \( \frac{18}{4} \):

\[ \frac{18}{4} - \frac{1}{4} = \frac{18 - 1}{4} = \frac{17}{4} \]

So, Mandy has \( \frac{17}{4} \) kg of apples left. We can also convert this to a mixed number:

\[ \frac{17}{4} = 4 \frac{1}{4} \]

Problem: John spends 12/7 hours fixing a watch and then spends an additional 3/9 hours polishing it. How many hours in total did he spent working on the watch?

GPT-4o:

First, we need to simplify the fractions involved. 

The fraction \( \frac{3}{9} \) can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
\[ \frac{3}{9} = \frac{3 \div 3}{9 \div 3} = \frac{1}{3} \]

Now, we need to add the two fractions \( \frac{12}{7} \) and \( \frac{1}{3} \). To do this, we need a common denominator. The least common multiple of 7 and 3 is 21.

Convert each fraction to have a denominator of 21:
\[ \frac{12}{7} = \frac{12 \times 3}{7 \times 3} = \frac{36}{21} \]
\[ \frac{1}{3} = \frac{1 \times 7}{3 \times 7} = \frac{7}{21} \]

Now, add the two fractions:
\[ \frac{36}{21} + \frac{7}{21} = \frac{36 + 7}{21} = \frac{43}{21} \]

So, John spent \( \frac{43}{21} \) hours in total working on the watch.

To find the total time John spent working on the watch, we need to add the time he spent fixing and polishing the watch to the time he spent adjusting its mechanism.

From the previous calculation, we know that John spent \( \frac{43}{21} \) hours fixing and polishing the watch. Now, we need to add \( \frac{12}{13} \) hours to this.

To add these fractions, we need a common denominator. The least common multiple of 21 and 13 is 273.

Convert each fraction to have a denominator of 273:
\[ \frac{43}{21} = \frac{43 \times 13}{21 \times 13} = \frac{559}{273} \]
\[ \frac{12}{13} = \frac{12 \times 21}{13 \times 21} = \frac{252}{273} \]

Now, add the two fractions:
\[ \frac{559}{273} + \frac{252}{273} = \frac{559 + 252}{273} = \frac{811}{273} \]

So, John spent \( \frac{811}{273} \) hours in total working on the watch.

First, we need to simplify the fraction \( \frac{3}{15} \). We can do this by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
\[ \frac{3}{15} = \frac{3 \div 3}{15 \div 3} = \frac{1}{5} \]

Now, we need to add the two fractions \( \frac{12}{7} \) and \( \frac{1}{5} \). To do this, we need a common denominator. The least common multiple of 7 and 5 is 35.

Convert each fraction to have a denominator of 35:
\[ \frac{12}{7} = \frac{12 \times 5}{7 \times 5} = \frac{60}{35} \]
\[ \frac{1}{5} = \frac{1 \times 7}{5 \times 7} = \frac{7}{35} \]

Now, add the two fractions:
\[ \frac{60}{35} + \frac{7}{35} = \frac{60 + 7}{35} = \frac{67}{35} \]

To determine how far Peggy is from her family in this new scenario, we need to subtract the distance she swam back from the distance she initially traveled.

1. Peggy initially swam \( \frac{5}{4} \) miles.
2. She swam back \( \frac{1}{15} \) miles.

First, we need to convert these fractions to a common denominator to perform the subtraction. The least common multiple of 4 and 15 is 60.

Convert \( \frac{5}{4} \) to a fraction with a denominator of 60:
\[ \frac{5}{4} = \frac{5 \times 15}{4 \times 15} = \frac{75}{60} \]

Convert \( \frac{1}{15} \) to a fraction with a denominator of 60:
\[ \frac{1}{15} = \frac{1 \times 4}{15 \times 4} = \frac{4}{60} \]

Now, subtract the distance she swam back:
\[ \frac{75}{60} - \frac{4}{60} = \frac{75 - 4}{60} = \frac{71}{60} \]

Problem: A farmer has a fields where he grows wheat. One part of the field is 4 acres and another part is 11/12 of an acre. How many acres in total does he use to grow wheat?

GPT-4o:

To find the total number of acres the farmer uses to grow wheat, we need to add the two parts of the field together.

The first part of the field is 4 acres.
The second part of the field is \( \frac{11}{12} \) of an acre.

We can add these two values directly:

\[ 4 + \frac{11}{12} \]

To add these, we can convert 4 into a fraction with a denominator of 12:

\[ 4 = \frac{48}{12} \]

Now, we add the two fractions:

\[ \frac{48}{12} + \frac{11}{12} = \frac{48 + 11}{12} = \frac{59}{12} \]

So, the total number of acres the farmer uses to grow wheat is \( \frac{59}{12} \) acres.

To convert \( \frac{59}{12} \) into a mixed number:

\[ \frac{59}{12} = 4 \frac{11}{12} \]

Problem: After measuring his fields, the farmer also remembered that he has an additional patch of land where he grows vegetables, which is 17/11 of an acre. With this additional patch included, what is his total land area in acres?

GPT-4o:

To find the total land area, we need to add the area of the additional patch of land to the total area used for growing wheat.

From the previous calculation, the total area used for growing wheat is \( \frac{59}{12} \) acres.

The additional patch of land for vegetables is \( \frac{17}{11} \) acres.

To add these two fractions, we need a common denominator. The least common multiple of 12 and 11 is 132.

First, convert \( \frac{59}{12} \) to a fraction with a denominator of 132:

\[ \frac{59}{12} = \frac{59 \times 11}{12 \times 11} = \frac{649}{132} \]

Next, convert \( \frac{17}{11} \) to a fraction with a denominator of 132:

\[ \frac{17}{11} = \frac{17 \times 12}{11 \times 12} = \frac{204}{132} \]

Now, add the two fractions:

\[ \frac{649}{132} + \frac{204}{132} = \frac{649 + 204}{132} = \frac{853}{132} \]

To simplify \( \frac{853}{132} \), we can convert it to a mixed number:

\[ \frac{853}{132} = 6 \frac{61}{132} \]

Since 61 and 132 have no common factors other than 1, \( \frac{61}{132} \) is already in its simplest form.

GPT-4o:

To find the corrected total land area in acres, we need to add the two parts of the field together.

The first part of the field is \( \frac{4}{9} \) of an acre.
The second part of the field is \( \frac{11}{12} \) of an acre.

To add these fractions, we need a common denominator. The least common multiple of 9 and 12 is 36.

Convert each fraction to have a denominator of 36:

\[ \frac{4}{9} = \frac{4 \times 4}{9 \times 4} = \frac{16}{36} \]

\[ \frac{11}{12} = \frac{11 \times 3}{12 \times 3} = \frac{33}{36} \]

Now, add the two fractions:

\[ \frac{16}{36} + \frac{33}{36} = \frac{16 + 33}{36} = \frac{49}{36} \]

So, the corrected total land area in acres is \( \frac{49}{36} \) acres.

\frac{11}{4} = \frac{11 \times 17}{4 \times 17} = \frac{187}{68}
\]

\[
\frac{5}{17} = \frac{5 \times 4}{17 \times 4} = \frac{20}{68}
\]

Now, we add the two fractions:

\[
\frac{187}{68} + \frac{20}{68} = \frac{187 + 20}{68} = \frac{207}{68}
\]

To simplify \( \frac{207}{68} \), we check if there is a common factor. The greatest common divisor (GCD) of 207 and 68 is 1, so the fraction is already in its simplest form.

Thus, the total amount of fabric used is \( \frac{207}{68} \) yards.

Problem: If the designer also used an additional 19/10 yards of golden fabric, how many yards of fabric did she use in total now?

GPT-4o:

To find the total amount of fabric used, we need to add the previously calculated total of \( \frac{207}{68} \) yards to the additional \( \frac{19}{10} \) yards of golden fabric.

First, we need to find a common denominator for the fractions \( \frac{207}{68} \) and \( \frac{19}{10} \). The denominators are 68 and 10. The least common multiple (LCM) of 68 and 10 is 340.

Next, we convert each fraction to have the common denominator of 340:

\[
\frac{207}{68} = \frac{207 \times 5}{68 \times 5} = \frac{1035}{340}
\]

\[
\frac{19}{10} = \frac{19 \times 34}{10 \times 34} = \frac{646}{340}
\]

Now, we add the two fractions:

\[
\frac{1035}{340} + \frac{646}{340} = \frac{1035 + 646}{340} = \frac{1681}{340}
\]

To simplify \( \frac{1681}{340} \), we check if there is a common factor. The greatest common divisor (GCD) of 1681 and 340 is 1, so the fraction is already in its simplest form.

Thus, the total amount of fabric used is \( \frac{1681}{340} \) yards.

### Answer: \( \frac{1681}{340} \) yards

Problem: If the dress designer initially used 11/4 yards of red fabric, but then decided to use only 5/5 yards of blue fabric, how many yards of fabric did she use in total?

GPT-4o:

To find the total amount of fabric used, we need to add the two fractions: \( \frac{11}{4} \) yards of red fabric and \( \frac{5}{5} \) yards of blue fabric.

First, simplify \( \frac{5}{5} \):

\[
\frac{5}{5} = 1
\]

Now, we add \( \frac{11}{4} \) and 1. To do this, we need to express 1 as a fraction with the same denominator as \( \frac{11}{4} \):

\[
1 = \frac{4}{4}
\]

Now, add the two fractions:

\[
\frac{11}{4} + \frac{4}{4} = \frac{11 + 4}{4} = \frac{15}{4}
\]

Thus, the total amount of fabric used is \( \frac{15}{4} \) yards.

Problem: Jacob has 11/2 feet long guitar wire. If he uses 5/16 feet of it to fix a guitar, how much wire is remaining?

GPT-4o:

To determine how much wire Jacob has remaining, we need to subtract the amount he used from the total amount he had.

First, let's convert the fractions to have a common denominator. The denominators are 2 and 16. The least common multiple of 2 and 16 is 16.

Convert \( \frac{11}{2} \) to a fraction with a denominator of 16:
\[ \frac{11}{2} = \frac{11 \times 8}{2 \times 8} = \frac{88}{16} \]

Now, subtract \( \frac{5}{16} \) from \( \frac{88}{16} \):
\[ \frac{88}{16} - \frac{5}{16} = \frac{88 - 5}{16} = \frac{83}{16} \]

So, the remaining wire is \( \frac{83}{16} \) feet.

GPT-4o:

To find out how much guitar wire Jacob has in total now, we need to add the remaining wire from before to the new wire he bought.

From the previous calculation, Jacob had \( \frac{83}{16} \) feet of wire remaining. He bought an additional \( \frac{3}{4} \) feet of wire.

First, let's convert \( \frac{3}{4} \) to a fraction with a denominator of 16:
\[ \frac{3}{4} = \frac{3 \times 4}{4 \times 4} = \frac{12}{16} \]

Now, add \( \frac{83}{16} \) and \( \frac{12}{16} \):
\[ \frac{83}{16} + \frac{12}{16} = \frac{83 + 12}{16} = \frac{95}{16} \]

To determine how much wire Jacob has remaining after using \( \frac{9}{16} \) feet, we need to subtract the amount he used from the total amount he had.

First, let's convert the fractions to have a common denominator. The denominators are 2 and 16. The least common multiple of 2 and 16 is 16.

Convert \( \frac{11}{2} \) to a fraction with a denominator of 16:
\[ \frac{11}{2} = \frac{11 \times 8}{2 \times 8} = \frac{88}{16} \]

Now, subtract \( \frac{9}{16} \) from \( \frac{88}{16} \):
\[ \frac{88}{16} - \frac{9}{16} = \frac{88 - 9}{16} = \frac{79}{16} \]

So, the remaining wire is \( \frac{79}{16} \) feet.

Problem: Samantha has a 4 fluid ounce tube of toothpaste. In one week, she uses 17/14 fluid ounces. How much toothpaste does she have left after that week?

GPT-4o:

To determine how much toothpaste Samantha has left after one week, we need to subtract the amount she used from the total amount she started with.

1. Samantha starts with 4 fluid ounces of toothpaste.
2. She uses \( \frac{17}{14} \) fluid ounces in one week.

First, let's convert 4 fluid ounces to a fraction with a common denominator of 14 to make the subtraction easier:
\[ 4 = \frac{4 \times 14}{14} = \frac{56}{14} \]

Now, subtract the amount she used from the total:
\[ \frac{56}{14} - \frac{17}{14} = \frac{56 - 17}{14} = \frac{39}{14} \]

So, Samantha has \( \frac{39}{14} \) fluid ounces of toothpaste left after one week.

To determine how much toothpaste Samantha has left after using \( \frac{12}{14} \) fluid ounces in one week, we need to subtract the amount she used from the total amount she started with.

1. Samantha starts with 4 fluid ounces of toothpaste.
2. She uses \( \frac{12}{14} \) fluid ounces in one week.

First, let's convert 4 fluid ounces to a fraction with a common denominator of 14 to make the subtraction easier:
\[ 4 = \frac{4 \times 14}{14} = \frac{56}{14} \]

Now, subtract the amount she used from the total:
\[ \frac{56}{14} - \frac{12}{14} = \frac{56 - 12}{14} = \frac{44}{14} \]

We can simplify \( \frac{44}{14} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
\[ \frac{44}{14} = \frac{44 \div 2}{14 \div 2} = \frac{22}{7} \]

Problem: Maria has 12 candies. She gives each of her 6 friends an equal amount of candies. Maria also has 20 stickers and she gives each of her 20 friends a sticker. How many candies and stickers does each friend get in total?

GPT-4o:

First, let's determine how many candies each of Maria's 6 friends receives. Maria has 12 candies and she gives them equally to her 6 friends:

\[
\frac{12 \text{ candies}}{6 \text{ friends}} = 2 \text{ candies per friend}
\]

Next, let's determine how many stickers each of Maria's 20 friends receives. Maria has 20 stickers and she gives them equally to her 20 friends:

\[
\frac{20 \text{ stickers}}{20 \text{ friends}} = 1 \text{ sticker per friend}
\]

Each of Maria's 6 friends receives 2 candies, and each of her 20 friends receives 1 sticker. Since the problem asks for the total number of candies and stickers each friend gets, we need to consider only the friends who receive both candies and stickers. However, since the groups of friends are different (6 friends for candies and 20 friends for stickers), we can only state the individual amounts each friend in each group receives.

### Answer: Each of Maria's 6 friends gets 2 candies, and each of her 20 friends gets 1 sticker.

Problem: During a rainy day, the first rainfall lasted for 4/13 hours, and the next rainfall was a little longer and lasted for 11/5 hours. How many hours did it rain in total?

GPT-4o:

To find the total duration of the rainfall, we need to add the two fractions representing the durations of the rainfalls.

First, let's convert the fractions to a common denominator. The fractions are \( \frac{4}{13} \) and \( \frac{11}{5} \).

The least common multiple (LCM) of 13 and 5 is 65. We will convert both fractions to have this common denominator.

For \( \frac{4}{13} \):
\[ \frac{4}{13} = \frac{4 \times 5}{13 \times 5} = \frac{20}{65} \]

For \( \frac{11}{5} \):
\[ \frac{11}{5} = \frac{11 \times 13}{5 \times 13} = \frac{143}{65} \]

Now, we add the two fractions:
\[ \frac{20}{65} + \frac{143}{65} = \frac{20 + 143}{65} = \frac{163}{65} \]

To simplify \( \frac{163}{65} \), we can convert it to a mixed number:
\[ \frac{163}{65} = 2 \frac{33}{65} \]

So, the total duration of the rainfall is \( 2 \frac{33}{65} \) hours.

### Answer: \( 2 \frac{33}{65} \) hours

Problem: After the first day of rainy weather, the following day also experienced rainfall. This time however, it lasted for only 11/19 hours. What is the total amount of hours it rained over the course of these two days?

GPT-4o:

To find the total amount of hours it rained over the course of the two days, we need to add the total rainfall from the first day to the rainfall from the second day.

From the previous calculation, we know that the total rainfall on the first day was \( 2 \frac{33}{65} \) hours. We can convert this mixed number to an improper fraction:
\[ 2 \frac{33}{65} = \frac{2 \times 65 + 33}{65} = \frac{130 + 33}{65} = \frac{163}{65} \]

The rainfall on the second day lasted \( \frac{11}{19} \) hours.

To add these two fractions, we need a common denominator. The least common multiple (LCM) of 65 and 19 is 1235. We will convert both fractions to have this common denominator.

For \( \frac{163}{65} \):
\[ \frac{163}{65} = \frac{163 \times 19}{65 \times 19} = \frac{3097}{1235} \]

For \( \frac{11}{19} \):
\[ \frac{11}{19} = \frac{11 \times 65}{19 \times 65} = \frac{715}{1235} \]

Now, we add the two fractions:
\[ \frac{3097}{1235} + \frac{715}{1235} = \frac{3097 + 715}{1235} = \frac{3812}{1235} \]

To simplify \( \frac{3812}{1235} \), we can convert it to a mixed number:
\[ \frac{3812}{1235} = 3 \frac{1107}{1235} \]

So, the total amount of hours it rained over the course of these two days is \( 3 \frac{1107}{1235} \) hours.

### Answer: \( 3 \frac{1107}{1235} \) hours

Expected answer: 3812/1235

Problem: Jane cuts 10/12 yards of fabric from a blanket. Then, she cuts an additional 10/10 yard. How many yards of fabric has she cut from the blanket in total?

GPT-4o:

First, let's simplify the fractions and then add them together.

Jane cuts 10/12 yards of fabric initially. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
\[ \frac{10}{12} = \frac{10 \div 2}{12 \div 2} = \frac{5}{6} \]

Next, Jane cuts an additional 10/10 yard, which simplifies to 1 yard:
\[ \frac{10}{10} = 1 \]

Now, we add the two amounts of fabric she cut:
\[ \frac{5}{6} + 1 \]

To add these fractions, we need a common denominator. The common denominator for 6 and 1 is 6. We convert 1 to a fraction with a denominator of 6:
\[ 1 = \frac{6}{6} \]

Now we can add the fractions:
\[ \frac{5}{6} + \frac{6}{6} = \frac{5 + 6}{6} = \frac{11}{6} \]

So, Jane has cut a total of \( \frac{11}{6} \) yards of fabric from the blanket.

Let's start by adding the fractions of fabric Jane has already cut and then include the additional cut.

From the previous calculation, we know Jane initially cut:
\[ \frac{5}{6} \text{ yards} \]
and
\[ 1 \text{ yard} \]

We already combined these to get:
\[ \frac{5}{6} + 1 = \frac{5}{6} + \frac{6}{6} = \frac{11}{6} \text{ yards} \]

Now, Jane cuts an additional \( \frac{4}{12} \) yard. We can simplify \( \frac{4}{12} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{4}{12} = \frac{4 \div 4}{12 \div 4} = \frac{1}{3} \]

Next, we need to add \( \frac{11}{6} \) and \( \frac{1}{3} \). To do this, we need a common denominator. The least common multiple of 6 and 3 is 6. We convert \( \frac{1}{3} \) to a fraction with a denominator of 6:
\[ \frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2}{6} \]

Now we can add the fractions:
\[ \frac{11}{6} + \frac{2}{6} = \frac{11 + 2}{6} = \frac{13}{6} \]

So, Jane has cut a total of \( \frac{13}{6} \) yards of fabric from the blanket.

To add these fractions, we need a common denominator. The common denominator for 12 and 1 is 12. We convert 1 to a fraction with a denominator of 12:
\[ 1 = \frac{12}{12} \]

Now we can add the fractions:
\[ \frac{11}{12} + \frac{12}{12} = \frac{11 + 12}{12} = \frac{23}{12} \]

To find the total amount of magic dust the fairy used, we need to add the two amounts together: \( \frac{11}{12} \) oz and \( \frac{9}{10} \) oz.

First, we need a common denominator to add these fractions. The least common multiple (LCM) of 12 and 10 is 60.

Convert \( \frac{11}{12} \) to a fraction with a denominator of 60:
\[ \frac{11}{12} = \frac{11 \times 5}{12 \times 5} = \frac{55}{60} \]

Then, she flies over to a nearby forest where she originally had 14/3 oz of magic dust. After using the dust over the field and apple trees, how much magic dust is left for the fairy now?

GPT-4o:

First, we need to determine the total amount of magic dust the fairy used over the enchanted field and the grove of enchanted apple trees. We already calculated this in the previous problem:

\[ \frac{11}{12} + \frac{9}{10} = \frac{109}{60} \]

Next, we need to subtract this amount from the original amount of magic dust the fairy had in the forest, which is \( \frac{14}{3} \) oz.

First, convert \( \frac{14}{3} \) to a fraction with a common denominator of 60:

\[ \frac{14}{3} = \frac{14 \times 20}{3 \times 20} = \frac{280}{60} \]

Now, subtract the amount of dust used from the original amount:

\[ \frac{280}{60} - \frac{109}{60} = \frac{280 - 109}{60} = \frac{171}{60} \]

Simplify the fraction \( \frac{171}{60} \):

\[ \frac{171}{60} = \frac{57}{20} \]

Problem: A word game assigns 3/11 of a point for each vowel used and 8/10 of a point for each consonant. If you use 1 vowel and 1 consonant, what will your score be?

GPT-4o:

To determine the total score for using 1 vowel and 1 consonant, we need to add the points assigned for each.

First, we calculate the points for the vowel:
\[ \text{Points for 1 vowel} = \frac{3}{11} \]

Next, we calculate the points for the consonant:
\[ \text{Points for 1 consonant} = \frac{8}{10} = 0.8 \]

Now, we add the points for the vowel and the consonant:
\[ \text{Total score} = \frac{3}{11} + 0.8 \]

To add these fractions, we need a common denominator. The least common multiple of 11 and 10 is 110. We convert each fraction to have this common denominator:

\[ \frac{3}{11} = \frac{3 \times 10}{11 \times 10} = \frac{30}{110} \]
\[ 0.8 = \frac{8}{10} = \frac{8 \times 11}{10 \times 11} = \frac{88}{110} \]

Now, we add the fractions:
\[ \frac{30}{110} + \frac{88}{110} = \frac{30 + 88}{110} = \frac{118}{110} \]

Simplifying the fraction:
\[ \frac{118}{110} = \frac{59}{55} \]

\[ \frac{19}{7} = \frac{19 \times 55}{7 \times 55} = \frac{1045}{385} \]

Now, we add the fractions:
\[ \frac{413}{385} + \frac{1045}{385} = \frac{413 + 1045}{385} = \frac{1458}{385} \]

To add these fractions, we need a common denominator. The least common multiple of 11 and 10 is 110. We convert each fraction to have this common denominator:

\[ \frac{5}{11} = \frac{5 \times 10}{11 \times 10} = \frac{50}{110} \]
\[ 0.8 = \frac{8}{10} = \frac{8 \times 11}{10 \times 11} = \frac{88}{110} \]

Now, we add the fractions:
\[ \frac{50}{110} + \frac{88}{110} = \frac{50 + 88}{110} = \frac{138}{110} \]

Simplifying the fraction:
\[ \frac{138}{110} = \frac{69}{55} \]

To determine how many pages the letter is now, we need to subtract the fraction of pages removed from the original length of the letter.

First, let's convert the mixed numbers to improper fractions for easier calculation:

The original length of the letter is \( \frac{4}{1} \), which is already an improper fraction.

The pages removed are \( \frac{14}{9} \).

Now, we need to subtract \( \frac{14}{9} \) from \( \frac{4}{1} \). To do this, we need a common denominator. The least common multiple of 1 and 9 is 9.

Convert \( \frac{4}{1} \) to a fraction with a denominator of 9:
\[ \frac{4}{1} = \frac{4 \times 9}{1 \times 9} = \frac{36}{9} \]

Now, subtract \( \frac{14}{9} \) from \( \frac{36}{9} \):
\[ \frac{36}{9} - \frac{14}{9} = \frac{36 - 14}{9} = \frac{22}{9} \]

So, the letter is now \( \frac{22}{9} \) pages long.

Problem: You decide to add some more content to your letter. If you add 7/12 of a page, how many pages will the letter be then?

GPT-4o:

To determine the new length of the letter after adding \( \frac{7}{12} \) of a page, we need to add this fraction to the current length of the letter, which is \( \frac{22}{9} \) pages.

First, we need a common denominator to add these fractions. The least common multiple of 9 and 12 is 36.

Convert \( \frac{22}{9} \) to a fraction with a denominator of 36:
\[ \frac{22}{9} = \frac{22 \times 4}{9 \times 4} = \frac{88}{36} \]

Convert \( \frac{7}{12} \) to a fraction with a denominator of 36:
\[ \frac{7}{12} = \frac{7 \times 3}{12 \times 3} = \frac{21}{36} \]

Now, add the two fractions:
\[ \frac{88}{36} + \frac{21}{36} = \frac{88 + 21}{36} = \frac{109}{36} \]

So, the letter will be \( \frac{109}{36} \) pages long.

### Answer: \(\frac{109}{36}\) pages

Problem: What if your original letter was slightly longer, being 15/1 pages in total, but you still removed the same 14/9 pages from it? How many pages would the letter be then?

GPT-4o:

To determine how many pages the letter is now, we need to subtract the fraction of pages removed from the new original length of the letter.

First, let's convert the mixed numbers to improper fractions for easier calculation:

The new original length of the letter is \( \frac{15}{1} \), which is already an improper fraction.

The pages removed are \( \frac{14}{9} \).

Now, we need to subtract \( \frac{14}{9} \) from \( \frac{15}{1} \). To do this, we need a common denominator. The least common multiple of 1 and 9 is 9.

Convert \( \frac{15}{1} \) to a fraction with a denominator of 9:
\[ \frac{15}{1} = \frac{15 \times 9}{1 \times 9} = \frac{135}{9} \]

Now, subtract \( \frac{14}{9} \) from \( \frac{135}{9} \):
\[ \frac{135}{9} - \frac{14}{9} = \frac{135 - 14}{9} = \frac{121}{9} \]

So, the letter is now \( \frac{121}{9} \) pages long.

### Answer: \(\frac{121}{9}\) pages

Expected answer: 121/9

Correct? Yes

Problem: Anne painted 16/20 of a table, and then Bob painted an additional 5/20 of the table. How much of the table has been painted in total?

GPT-4o:

To determine how much of the table has been painted in total, we need to add the fractions of the table that Anne and Bob painted.

Anne painted \( \frac{16}{20} \) of the table.
Bob painted \( \frac{5}{20} \) of the table.

We add these fractions together:
\[
\frac{16}{20} + \frac{5}{20} = \frac{16 + 5}{20} = \frac{21}{20}
\]

Since \( \frac{21}{20} \) is an improper fraction, it means that more than the entire table has been painted. Converting \( \frac{21}{20} \) to a mixed number:
\[
\frac{21}{20} = 1 \frac{1}{20}
\]

This indicates that the entire table has been painted, and an additional \( \frac{1}{20} \) of the table has been painted over.

### Answer: \( \frac{21}{20} \) or 1 \( \frac{1}{20} \)

Expected answer: 21/20

Problem: The star Alpha shines 17/3 times brighter than an average star, while the star Bravo shines 20/16 times as bright. How much brighter are both stars compared to an average star if you add up the relative brightness of these two stars?

GPT-4o:

First, let's determine the relative brightness of each star compared to an average star.

For the star Alpha:
Alpha shines \( \frac{17}{3} \) times brighter than an average star.

For the star Bravo:
Bravo shines \( \frac{20}{16} \) times as bright as an average star. Simplifying \( \frac{20}{16} \):
\[ \frac{20}{16} = \frac{5}{4} \]

Now, we need to add the relative brightness of both stars:
\[ \frac{17}{3} + \frac{5}{4} \]

To add these fractions, we need a common denominator. The least common multiple of 3 and 4 is 12.

Convert \( \frac{17}{3} \) to a fraction with a denominator of 12:
\[ \frac{17}{3} = \frac{17 \times 4}{3 \times 4} = \frac{68}{12} \]

Convert \( \frac{5}{4} \) to a fraction with a denominator of 12:
\[ \frac{5}{4} = \frac{5 \times 3}{4 \times 3} = \frac{15}{12} \]

Now, add the fractions:
\[ \frac{68}{12} + \frac{15}{12} = \frac{68 + 15}{12} = \frac{83}{12} \]

Thus, the combined relative brightness of both stars compared to an average star is:
\[ \frac{83}{12} \]

### Answer: \(\frac{83}{12}\) times brighter

Expected answer: 83/12

Correct? Yes

🔗 Follow-up

Problem: Taking into account the previous situation, if we adjust the brightness of star Alpha such that it only shines 8/3 times brighter than an average star instead of 17/3 times, how much brighter would Alpha and Bravo combined be in comparison to an average star?

GPT-4o:

First, let's determine the new relative brightness of star Alpha and the relative brightness of star Bravo.

For the adjusted star Alpha:
Alpha now shines \( \frac{8}{3} \) times brighter than an average star.

For the star Bravo:
Bravo shines \( \frac{5}{4} \) times as bright as an average star (as previously calculated).

Now, we need to add the relative brightness of both stars:
\[ \frac{8}{3} + \frac{5}{4} \]

To add these fractions, we need a common denominator. The least common multiple of 3 and 4 is 12.

Convert \( \frac{8}{3} \) to a fraction with a denominator of 12:
\[ \frac{8}{3} = \frac{8 \times 4}{3 \times 4} = \frac{32}{12} \]

Convert \( \frac{5}{4} \) to a fraction with a denominator of 12:
\[ \frac{5}{4} = \frac{5 \times 3}{4 \times 3} = \frac{15}{12} \]

Now, add the fractions:
\[ \frac{32}{12} + \frac{15}{12} = \frac{32 + 15}{12} = \frac{47}{12} \]

Thus, the combined relative brightness of both stars compared to an average star is:
\[ \frac{47}{12} \]

### Answer: \(\frac{47}{12}\) times brighter

Problem: There are 17/20 kg of red apples and 18/8 kg of green apples in a grocery store. How many kilograms of apples are in the store in total?

GPT-4o:

First, we need to convert the fractions to have a common denominator or convert them to decimals for easier addition.

For the red apples:
\[ \frac{17}{20} \]

For the green apples:
\[ \frac{18}{8} = \frac{9}{4} \]

To add these fractions, we can convert them to decimals:
\[ \frac{17}{20} = 0.85 \]
\[ \frac{9}{4} = 2.25 \]

Now, we add the two quantities:
\[ 0.85 + 2.25 = 3.10 \]

So, the total weight of the apples in the store is 3.10 kg.

### Answer: 3.10 kg

Expected answer: 31/10

🔗 Problem

Problem: If a bus drives 12/20 of a mile then goes an additional 12/12 of a mile, how many miles did the bus travel in total?

GPT-4o:

First, let's simplify the fractions to understand the distances traveled.

The bus drives \( \frac{12}{20} \) of a mile. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{12 \div 4}{20 \div 4} = \frac{3}{5} \]

Next, the bus drives \( \frac{12}{12} \) of a mile. Since the numerator and the denominator are the same, this fraction simplifies to 1:
\[ \frac{12}{12} = 1 \]

Now, we add the two distances together:
\[ \frac{3}{5} + 1 \]

To add these fractions, we need a common denominator. The common denominator for 5 and 1 is 5. We can rewrite 1 as \( \frac{5}{5} \):
\[ \frac{3}{5} + \frac{5}{5} = \frac{3 + 5}{5} = \frac{8}{5} \]

The fraction \( \frac{8}{5} \) can also be expressed as a mixed number:
\[ \frac{8}{5} = 1 \frac{3}{5} \]

So, the total distance the bus traveled is \( \frac{8}{5} \) miles or 1 \( \frac{3}{5} \) miles.

### Answer: \( \frac{8}{5} \) miles or 1 \( \frac{3}{5} \) miles.

Problem: In the first hour, a shark swims 3/9 miles and in the second hour height increases its speed to swim 13/5 miles. How many miles does the shark swim in total in these two hours?

GPT-4o:

To find the total distance the shark swims in two hours, we need to add the distances swum in each hour.

First, let's simplify the distance swum in the first hour:
\[ \frac{3}{9} = \frac{1}{3} \text{ miles} \]

Next, we have the distance swum in the second hour:
\[ \frac{13}{5} \text{ miles} \]

Now, we add these two distances together:
\[ \frac{1}{3} + \frac{13}{5} \]

To add these fractions, we need a common denominator. The least common multiple of 3 and 5 is 15. We convert each fraction to have this common denominator:
\[ \frac{1}{3} = \frac{1 \times 5}{3 \times 5} = \frac{5}{15} \]
\[ \frac{13}{5} = \frac{13 \times 3}{5 \times 3} = \frac{39}{15} \]

Now, we add the fractions:
\[ \frac{5}{15} + \frac{39}{15} = \frac{5 + 39}{15} = \frac{44}{15} \]

So, the total distance the shark swims in two hours is:
\[ \frac{44}{15} \text{ miles} \]

### Answer: \(\frac{44}{15}\) miles

Problem: After swimming for two hours, the shark decides to swim for a third hour and it covers a distance of 14/9 miles. What is the total distance covered by the shark in these three hours?

GPT-4o:

To find the total distance covered by the shark in three hours, we need to add the distances swum in each hour.

From the previous calculation, we know the shark swam:
\[ \frac{44}{15} \text{ miles} \]
in the first two hours.

In the third hour, the shark swims:
\[ \frac{14}{9} \text{ miles} \]

To add these fractions, we need a common denominator. The least common multiple of 15 and 9 is 45. We convert each fraction to have this common denominator:
\[ \frac{44}{15} = \frac{44 \times 3}{15 \times 3} = \frac{132}{45} \]
\[ \frac{14}{9} = \frac{14 \times 5}{9 \times 5} = \frac{70}{45} \]

Now, we add the fractions:
\[ \frac{132}{45} + \frac{70}{45} = \frac{132 + 70}{45} = \frac{202}{45} \]

So, the total distance the shark swims in three hours is:
\[ \frac{202}{45} \text{ miles} \]

Problem: In reconsideration of the first hour, what if the shark only swam for 3/7 miles instead of 3/9 miles, but still swam 13/5 miles in the the second hour. What would be the total distance covered in these two hours then?

GPT-4o:

To find the total distance the shark swims in two hours with the updated distance for the first hour, we need to add the distances swum in each hour.

First, let's note the distance swum in the first hour:
\[ \frac{3}{7} \text{ miles} \]

Next, we have the distance swum in the second hour:
\[ \frac{13}{5} \text{ miles} \]

Now, we add these two distances together:
\[ \frac{3}{7} + \frac{13}{5} \]

To add these fractions, we need a common denominator. The least common multiple of 7 and 5 is 35. We convert each fraction to have this common denominator:
\[ \frac{3}{7} = \frac{3 \times 5}{7 \times 5} = \frac{15}{35} \]
\[ \frac{13}{5} = \frac{13 \times 7}{5 \times 7} = \frac{91}{35} \]

Now, we add the fractions:
\[ \frac{15}{35} + \frac{91}{35} = \frac{15 + 91}{35} = \frac{106}{35} \]

So, the total distance the shark swims in two hours is:

Problem: A drummer hits a rhythm where they hit once every 17/17 seconds for the first beat and then 2/12 seconds for the second beat. How long does it take for the drummer to hit the two beats together?

GPT-4o:

First, let's simplify the fractions for each beat.

For the first beat:
\[
\frac{17}{17} = 1 \text{ second}
\]

For the second beat:
\[
\frac{2}{12} = \frac{1}{6} \text{ seconds}
\]

To find the total time it takes for the drummer to hit the two beats together, we add the time for each beat:
\[
1 \text{ second} + \frac{1}{6} \text{ seconds}
\]

To add these, we need a common denominator. The common denominator for 1 and \(\frac{1}{6}\) is 6. We convert 1 second to a fraction with a denominator of 6:
\[
1 = \frac{6}{6}
\]

Now, we add the fractions:
\[
\frac{6}{6} + \frac{1}{6} = \frac{6 + 1}{6} = \frac{7}{6} \text{ seconds}
\]

Thus, the total time it takes for the drummer to hit the two beats together is:
\[
\frac{7}{6} \text{ seconds}
\]

### Answer: \(\frac{7}{6}\) seconds

GPT-4o:

First, let's simplify the fractions for each beat.

For the first beat:
\[
\frac{16}{17} \text{ seconds}
\]

For the second beat:
\[
\frac{2}{12} = \frac{1}{6} \text{ seconds}
\]

To find the total time it takes for the drummer to hit the two beats together, we add the time for each beat:
\[
\frac{16}{17} \text{ seconds} + \frac{1}{6} \text{ seconds}
\]

To add these fractions, we need a common denominator. The least common multiple (LCM) of 17 and 6 is 102. We convert each fraction to have a denominator of 102.

Convert \(\frac{16}{17}\) to a fraction with a denominator of 102:
\[
\frac{16}{17} = \frac{16 \times 6}{17 \times 6} = \frac{96}{102}
\]

Convert \(\frac{1}{6}\) to a fraction with a denominator of 102:
\[
\frac{1}{6} = \frac{1 \times 17}{6 \times 17} = \frac{17}{102}
\]

Now, we add the fractions:
\[
\frac{96}{102} + \frac{17}{102} = \frac{96 + 17}{102} = \frac{113}{102} \text{ seconds}
\]

Thus, the total time it takes for the drummer to hit the two beats together is:

Problem: If a fireplace burns 12/17 cord of wood in the morning and 8/19 cord in the evening, what is the total cord of wood it burns in a day?

GPT-4o:

To find the total cord of wood burned in a day, we need to add the fractions 12/17 and 8/19.

First, we need a common denominator for the fractions. The least common multiple (LCM) of 17 and 19 is 323 (since 17 and 19 are both prime numbers, their LCM is their product).

Next, we convert each fraction to have the common denominator of 323:

\[
\frac{12}{17} = \frac{12 \times 19}{17 \times 19} = \frac{228}{323}
\]

\[
\frac{8}{19} = \frac{8 \times 17}{19 \times 17} = \frac{136}{323}
\]

Now, we add the two fractions:

\[
\frac{228}{323} + \frac{136}{323} = \frac{228 + 136}{323} = \frac{364}{323}
\]

Since \(\frac{364}{323}\) is an improper fraction, we can convert it to a mixed number:

\[
\frac{364}{323} = 1 + \frac{41}{323}
\]

Thus, the total cord of wood burned in a day is:

\[
1 + \frac{41}{323}

GPT-4o:

To find the total cord of wood burned in one full day, we need to add the wood burned in the morning, evening, and night.

From the previous calculation, we know the fireplace burns \(1 + \frac{41}{323}\) cords of wood during the day (morning and evening combined).

Now, we need to add the additional \(\frac{19}{20}\) cord of wood burned at night.

First, we convert \(1 + \frac{41}{323}\) to an improper fraction:

\[
1 + \frac{41}{323} = \frac{323}{323} + \frac{41}{323} = \frac{364}{323}
\]

Next, we need a common denominator to add \(\frac{364}{323}\) and \(\frac{19}{20}\). The least common multiple (LCM) of 323 and 20 is 6460.

Convert each fraction to have the common denominator of 6460:

\[
\frac{364}{323} = \frac{364 \times 20}{323 \times 20} = \frac{7280}{6460}
\]

\[
\frac{19}{20} = \frac{19 \times 323}{20 \times 323} = \frac{6137}{6460}
\]

Now, add the two fractions:

\[
\frac{7280}{6460} + \frac{6137}{6460} = \frac{7280 + 6137}{6460} = \frac{13417}{6460}
\]

Since \(\frac{13417}{6460}\) is an improper fraction, we can convert it to a mixed number:

\[
\frac{13417}{6460} = 2 + \frac{3497}{6460}
\]

Thus, the total cord of wood burned in one full day is:

\[
2 + \frac{3497}{6460}

GPT-4o:

To find the new total distance of the butterfly's flight, we need to add the distances of the two segments with the updated first segment.

First segment: \( \frac{18}{12} \) miles
Second segment: \( \frac{9}{17} \) miles

First, simplify \( \frac{18}{12} \):

\[
\frac{18}{12} = \frac{18 \div 6}{12 \div 6} = \frac{3}{2}
\]

Now, we need to add \( \frac{3}{2} \) and \( \frac{9}{17} \). To do this, we need a common denominator. The least common multiple (LCM) of 2 and 17 is 34.

Convert each fraction to have the common denominator of 34:

\[
\frac{3}{2} = \frac{3 \times 17}{2 \times 17} = \frac{51}{34}
\]

\[

Problem: Instead of the distance between the first two cities on the map being 13/10 inches, suppose it is 13/7 inches. Keeping the distance from the second city to the third city the same at 14/15 inches, what would then be the total distance between the three cities on the map?

GPT-4o:

To find the total distance Jenna measured between the three cities with the new distances, we need to add the two distances together.

First, we have the distance between the first and second cities:
\[ \frac{13}{7} \]

Next, we have the distance between the second and third cities:
\[ \frac{14}{15} \]

To add these fractions, we need a common denominator. The least common multiple of 7 and 15 is 105.

Convert each fraction to have a denominator of 105:
\[ \frac{13}{7} = \frac{13 \times 15}{7 \times 15} = \frac{195}{105} \]
\[ \frac{14}{15} = \frac{14 \times 7}{15 \times 7} = \frac{98}{105} \]

Now, add the fractions:
\[ \frac{195}{105} + \frac{98}{105} = \frac{195 + 98}{105} = \frac{293}{105} \]

So, the total distance Jenna measured between the three cities on the map is:
\[ \frac{293}{105} \] inches.

### Answer: \(\frac{293}{105}\) inches

Problem: A helium balloon rises at a rate of 13/6 feet per second. After a gust of wind, its speed increases by 3/16 feet per second. What is the new speed of the balloon in feet per second?

GPT-4o:

To find the new speed of the helium balloon, we need to add the initial speed to the increase in speed caused by the gust of wind.

The initial speed of the balloon is \( \frac{13}{6} \) feet per second.
The increase in speed due to the gust of wind is \( \frac{3}{16} \) feet per second.

To add these two fractions, we need a common denominator. The least common multiple of 6 and 16 is 48.

First, convert \( \frac{13}{6} \) to a fraction with a denominator of 48:
\[ \frac{13}{6} = \frac{13 \times 8}{6 \times 8} = \frac{104}{48} \]

Next, convert \( \frac{3}{16} \) to a fraction with a denominator of 48:
\[ \frac{3}{16} = \frac{3 \times 3}{16 \times 3} = \frac{9}{48} \]

Now, add the two fractions:
\[ \frac{104}{48} + \frac{9}{48} = \frac{104 + 9}{48} = \frac{113}{48} \]

So, the new speed of the balloon is \( \frac{113}{48} \) feet per second.

### Answer: \(\frac{113}{48}\)

Expected answer: 113/48

Correct? Yes

Problem: If a second identical helium balloon behaving exactly like the first one rises alongside, what would be their total combined speed in feet per second?

GPT-4o:

If a second identical helium balloon rises alongside the first one, and both balloons have the same speed, we need to find the combined speed of the two balloons.

From the previous calculation, the speed of one balloon is \( \frac{113}{48} \) feet per second.

To find the combined speed of the two balloons, we simply add the speed of the first balloon to the speed of the second balloon:
\[ \frac{113}{48} + \frac{113}{48} = \frac{113 + 113}{48} = \frac{226}{48} \]

We can simplify this fraction by finding the greatest common divisor (GCD) of 226 and 48. The GCD of 226 and 48 is 2.

So, we divide both the numerator and the denominator by 2:
\[ \frac{226 \div 2}{48 \div 2} = \frac{113}{24} \]

Thus, the total combined speed of the two balloons is \( \frac{113}{24} \) feet per second.

### Answer: \(\frac{113}{24}\)

Problem: Scarlett has 16/10 gallons of red paint. If she uses 1/20 of a gallon for a small art project, how many gallons of red paint will she have left?

GPT-4o:

First, let's convert the given fractions to a common denominator to make the calculations easier.

Scarlett has \( \frac{16}{10} \) gallons of red paint. We can simplify this fraction:
\[ \frac{16}{10} = \frac{8}{5} \]

She uses \( \frac{1}{20} \) of a gallon for a small art project.

To subtract these fractions, we need a common denominator. The least common multiple of 5 and 20 is 20.

Convert \( \frac{8}{5} \) to a fraction with a denominator of 20:
\[ \frac{8}{5} = \frac{8 \times 4}{5 \times 4} = \frac{32}{20} \]

Now, subtract \( \frac{1}{20} \) from \( \frac{32}{20} \):
\[ \frac{32}{20} - \frac{1}{20} = \frac{32 - 1}{20} = \frac{31}{20} \]

So, Scarlett will have \( \frac{31}{20} \) gallons of red paint left.

### Answer: \(\frac{31}{20}\) gallons

Problem: After finishing the small art project, Scarlett decides to mix the remaining red paint with 5/7 gallons of yellow paint to make orange paint. How many gallons of paint does she have now?

GPT-4o:

Scarlett has \( \frac{31}{20} \) gallons of red paint left after her small art project. She decides to mix this with \( \frac{5}{7} \) gallons of yellow paint.

To find the total amount of paint, we need to add these two fractions. First, we need a common denominator. The least common multiple of 20 and 7 is 140.

Convert \( \frac{31}{20} \) to a fraction with a denominator of 140:
\[ \frac{31}{20} = \frac{31 \times 7}{20 \times 7} = \frac{217}{140} \]

Convert \( \frac{5}{7} \) to a fraction with a denominator of 140:
\[ \frac{5}{7} = \frac{5 \times 20}{7 \times 20} = \frac{100}{140} \]

Now, add the two fractions:
\[ \frac{217}{140} + \frac{100}{140} = \frac{217 + 100}{140} = \frac{317}{140} \]

So, Scarlett has \( \frac{317}{140} \) gallons of paint now.

Problem: Suppose Scarlett initially had 16/10 gallons of red paint. But this time, she uses 2/20 of a gallon for her small project instead. How many gallons of red paint does she have left now?

GPT-4o:

First, let's simplify the initial amount of red paint Scarlett has:
\[ \frac{16}{10} = \frac{8}{5} \]

She uses \( \frac{2}{20} \) of a gallon for her small project. We can simplify \( \frac{2}{20} \):
\[ \frac{2}{20} = \frac{1}{10} \]

To subtract these fractions, we need a common denominator. The least common multiple of 5 and 10 is 10.

Convert \( \frac{8}{5} \) to a fraction with a denominator of 10:
\[ \frac{8}{5} = \frac{8 \times 2}{5 \times 2} = \frac{16}{10} \]

Now, subtract \( \frac{1}{10} \) from \( \frac{16}{10} \):
\[ \frac{16}{10} - \frac{1}{10} = \frac{16 - 1}{10} = \frac{15}{10} \]

We can simplify \( \frac{15}{10} \):
\[ \frac{15}{10} = \frac{3}{2} \]

So, Scarlett will have \( \frac{3}{2} \) gallons of red paint left.

Problem: Susie has a box of 12 chocolate bars. She decides to eat 2/5 of a chocolate bar herself. How many chocolate bars are left in the box?

GPT-4o:

First, we need to determine how many chocolate bars Susie eats. She eats \( \frac{2}{5} \) of a chocolate bar.

Next, we subtract the amount Susie eats from the total number of chocolate bars in the box. The total number of chocolate bars is 12.

So, the calculation is:
\[ 12 - \frac{2}{5} \]

To perform this subtraction, we can convert 12 into a fraction with a common denominator of 5:
\[ 12 = \frac{60}{5} \]

Now, we subtract \( \frac{2}{5} \) from \( \frac{60}{5} \):
\[ \frac{60}{5} - \frac{2}{5} = \frac{60 - 2}{5} = \frac{58}{5} \]

Finally, we convert \( \frac{58}{5} \) back to a mixed number:
\[ \frac{58}{5} = 11 \frac{3}{5} \]

So, Susie has \( 11 \frac{3}{5} \) chocolate bars left in the box.

Problem: Susie has a box of 12 chocolate bars. She decides to eat 2/5 of a chocolate bar herself. Then, her friend Lucy takes a further 19/11 chocolate bars. How many chocolate bars are left in the box after Lucy takes some?

GPT-4o:

First, we need to determine how many chocolate bars Susie and Lucy eat in total.

Susie eats \( \frac{2}{5} \) of a chocolate bar.

Lucy takes \( \frac{19}{11} \) chocolate bars.

Next, we need to add these two amounts together:
\[ \frac{2}{5} + \frac{19}{11} \]

To add these fractions, we need a common denominator. The least common multiple of 5 and 11 is 55.

Convert each fraction to have a denominator of 55:
\[ \frac{2}{5} = \frac{2 \times 11}{5 \times 11} = \frac{22}{55} \]
\[ \frac{19}{11} = \frac{19 \times 5}{11 \times 5} = \frac{95}{55} \]

Now, add the fractions:
\[ \frac{22}{55} + \frac{95}{55} = \frac{22 + 95}{55} = \frac{117}{55} \]

Next, we convert \( \frac{117}{55} \) to a mixed number:
\[ \frac{117}{55} = 2 \frac{7}{55} \]

So, Susie and Lucy together eat \( 2 \frac{7}{55} \) chocolate bars.

Now, we subtract this amount from the total number of chocolate bars in the box, which is 12:
\[ 12 - 2 \frac{7}{55} \]

Convert 12 to a fraction with a denominator of 55:
\[ 12 = \frac{660}{55} \]

Subtract \( 2 \frac{7}{55} \) from \( \frac{660}{55} \):
\[ \frac{660}{55} - \frac{117}{55} = \frac{660 - 117}{55} = \frac{543}{55} \]

Convert \( \frac{543}{55} \) back to a mixed number:
\[ \frac{543}{55} = 9 \frac{48}{55} \]

So, there are \( 9 \frac{48}{55} \) chocolate bars left in the box.

First, we need to determine how many chocolate bars Susie eats. She eats \( \frac{2}{13} \) of a chocolate bar.

Next, we subtract the amount Susie eats from the total number of chocolate bars in the box. The total number of chocolate bars is 12.

So, the calculation is:
\[ 12 - \frac{2}{13} \]

To perform this subtraction, we can convert 12 into a fraction with a common denominator of 13:
\[ 12 = \frac{156}{13} \]

Now, we subtract \( \frac{2}{13} \) from \( \frac{156}{13} \):
\[ \frac{156}{13} - \frac{2}{13} = \frac{156 - 2}{13} = \frac{154}{13} \]

Finally, we convert \( \frac{154}{13} \) back to a whole number:
\[ \frac{154}{13} = 11 \frac{11}{13} \]

Problem: A plane is flying at an altitude of 2 miles, then it descends by 10/15 of a mile. What is the new altitude of the plane?

GPT-4o:

To find the new altitude of the plane, we need to subtract the descent from the initial altitude.

1. The initial altitude of the plane is 2 miles.
2. The plane descends by \( \frac{10}{15} \) of a mile.

First, simplify \( \frac{10}{15} \):
\[ \frac{10}{15} = \frac{2 \times 5}{3 \times 5} = \frac{2}{3} \]

Now, subtract \( \frac{2}{3} \) of a mile from 2 miles:
\[ 2 - \frac{2}{3} \]

To perform this subtraction, convert 2 into a fraction with a common denominator of 3:
\[ 2 = \frac{6}{3} \]

Now subtract:
\[ \frac{6}{3} - \frac{2}{3} = \frac{6 - 2}{3} = \frac{4}{3} \]

Convert \( \frac{4}{3} \) back to a mixed number:
\[ \frac{4}{3} = 1 \frac{1}{3} \]

Problem: A colonial fireplace burns firewood at a rate of 4/15 cords per hour in the early morning. In the late night, the rate increases to 14/15 cords per hour. How much firewood does the fireplace burn in total in one hour split between the early morning and late night?

GPT-4o:

To determine the total amount of firewood burned in one hour split between the early morning and late night, we need to add the rates at which the firewood is burned during these times.

The rate of firewood burned in the early morning is:
\[ \frac{4}{15} \text{ cords per hour} \]

The rate of firewood burned in the late night is:
\[ \frac{14}{15} \text{ cords per hour} \]

To find the total amount of firewood burned in one hour, we add these two rates together:
\[ \frac{4}{15} + \frac{14}{15} \]

Since the denominators are the same, we can directly add the numerators:
\[ \frac{4 + 14}{15} = \frac{18}{15} \]

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
\[ \frac{18 \div 3}{15 \div 3} = \frac{6}{5} \]

Thus, the total amount of firewood burned in one hour split between the early morning and late night is:

First, we add the rates for the early morning and late night:
\[ \frac{4}{15} + \frac{14}{15} = \frac{18}{15} = \frac{6}{5} \text{ cords per hour} \]

Next, we add the rate for the peak hours:
\[ \frac{6}{5} + \frac{6}{5} \]

Since the denominators are the same, we can directly add the numerators:

Problem: An alien travelled 9/20 of a light year towards earth then decided to move forward another 11/7 light years. How many light years has the alien travelled in total?

GPT-4o:

To find the total distance the alien has traveled, we need to add the two distances together.

First, we have the distance traveled initially:
\[ \frac{9}{20} \text{ light years} \]

Next, we have the additional distance traveled:
\[ \frac{11}{7} \text{ light years} \]

To add these fractions, we need a common denominator. The least common multiple of 20 and 7 is 140. We convert each fraction to have this common denominator:

\[ \frac{9}{20} = \frac{9 \times 7}{20 \times 7} = \frac{63}{140} \]
\[ \frac{11}{7} = \frac{11 \times 20}{7 \times 20} = \frac{220}{140} \]

Now, we add the two fractions:
\[ \frac{63}{140} + \frac{220}{140} = \frac{63 + 220}{140} = \frac{283}{140} \]

To simplify \(\frac{283}{140}\), we can convert it to a mixed number:

To find the total distance the alien has traveled, we need to add the three distances together.

First, we already calculated the initial part of the journey:
\[ \frac{9}{20} + \frac{11}{7} = \frac{283}{140} \]

Next, we need to add the additional distance traveled:
\[ \frac{14}{2} = 7 \text{ light years} \]

Now, we add this to the previous total:
\[ \frac{283}{140} + 7 \]

To add these, we convert 7 to a fraction with the same denominator:
\[ 7 = \frac{7 \times 140}{140} = \frac{980}{140} \]

Now, we add the two fractions:
\[ \frac{283}{140} + \frac{980}{140} = \frac{283 + 980}{140} = \frac{1263}{140} \]

To simplify \(\frac{1263}{140}\), we can convert it to a mixed number:
\[ \frac{1263}{140} = 9 \frac{3}{140} \]

To add these, we need a common denominator. The common denominator for 20 and 1 is 20. We convert 1 to a fraction with a denominator of 20:
\[ 1 = \frac{20}{20} \]

Now, we add the fractions:
\[ \frac{9}{20} + \frac{20}{20} = \frac{9 + 20}{20} = \frac{29}{20} \]

To simplify \(\frac{29}{20}\), we can convert it to a mixed number:

\[ \frac{10}{2} = 5 \]

Next, we add this to \( \frac{17}{7} \):
\[ 5 + \frac{17}{7} \]

To add these fractions, we need a common denominator. The common denominator for 1 and 7 is 7. We can rewrite 5 as a fraction with a denominator of 7:
\[ 5 = \frac{35}{7} \]

Now, we add the fractions:
\[ \frac{35}{7} + \frac{17}{7} = \frac{35 + 17}{7} = \frac{52}{7} \]

So, Bob has \( \frac{52}{7} \) cucumbers in total.
